Convecting Forcing has been dominating Atmospheric Circulation in the NH throughout the whole previous year including Winter 2017-18.

26 Feb 2018

Using Temperature as the only variable, we can claim that we have experienced a strong variation between seasons this Winter 2017-18. However, based on the behaviour of the Polar Jet Stream, this year we have not had any seasonal change. To the extend of keep seeing from Summer and through the NH Winter, how the Arctic circulation has been unable to hold its position against intrusions of warm masses of mid-latitudinal air bending the Polar Jet stream inside Arctic latitudes.

The observation of such pattern throughout an entire yearly cycle shows to support the assessments published previously:

An increase in the amount of energy being in “free” state means that kinetic processes will increasingly dominate thermodynamic processes, inducing a transition in our Seasonal and Climatic regimes from being driven by Orbital Positioning to be driven by more erratic Kinetic processes.

An increase in the role of Convective Forcing dominating atmospheric circulation has been one of the main conclusions identified in previous assessments since 2014.

The debate on climate uses half truths and it is painful to keep quiet, though it could be the best option for my own good being in a period of transition looking into job opportunities or into forms of economic support.

The conclusions reached after 17 years analysing environmental synergies can be summarised as follows (all arguments have been covered throughout the publications found in this blog and my profile at researchgate. See main page/home for a full index):

1- Models confuse the science in which those are applied. Factions opposed in views will not come together by using models. And even there is no need for it. Darwin did not need an algorithm and a model to identify genetic evolution. The observational evidence was so strong that unified the scientific community. And evolution is a process comparable with climate, reacts to pressures.

2-Arctic Amplification takes an assumption open for discussion: “sea ice acts as a barrier for the heat transport from the ocean to the atmosphere.” Actually, sea ice acts as a barrier for the heat transport *from the atmosphere to the ocean. The line of research offered taking Arctic SST as responsible for warming processes is not considering the thermodynamics behind changes in phase (liquid/solid/gas) and the difference between condensible and not condensible GHGs. Heat moves between locations AND phases. SST warming the atmosphere would loose heat, thus forming ice.

3- Between global warming and global cooling there is global mixing

4- Anthropogenic link has reduced CxHxOx and increased CxOx+HxOx, albedo, …

The mere identification of seeing: numbers of trees decreased over 46% from wild ecosystems being affected through time due to agriculture, increased levels of urbanization, deforestation, same for soil degradation, decrease in O2 conc, and an increase in GHG, can not be left out of the equation when considering what it is and what it is not “natural variability”, and the future expected for our thermodynamic planetary system.

Our planet is getting fat on GHG, lacking O2, space to breath and capacity to fix and store energy. Biology integrates all components in an ecosystem, yet it is missing in climatology assessments.


It is that simple.

There are no other reasons justifying an increase in convective forcing:

Research Framework

The question  driving the whole debate on Climatic Deviations from “a Normal”, or Climatic Drift, focus most of the methodologies on temperature.

However I have followed a different approach in my analyses looking at Gradients of Energy in all its forms. That is why in 2014 I offered my thoughts as a theory of practical applications.

Energy fuels the work done by warm masses of air displacing colder masses of air in their path. That increases mixing patterns generating anomalies in temperature.

Behind an increase in the amount of work carried out by masses of air there is an increase in the energy fuelling such dynamics. Energy can only be transferred, not created or destroyed. So more work means more energy in circulation. More energy in circulation can only be sustained by a substance carrying it. Either if we consider that the energy driving anomalies comes from the Sun or from the Oceans, the carrier has to be in the atmosphere in order for the energy to produce work. And the body loosing heat cools down.

E.g. A corridor of wind across the Arctic is triggered by a conversion of Temperature into work, convection and advection, which are the result of mixing masses of air (addressed in the publication “A climate between Waters”). As I have published in previous analyses, such Trans-Arctic connection between Atlantic and Pacific Basins is part of a pattern increasing the mixing ratio between masses of air otherwise separated by thermal compartmentalization, like the Polar Jet Stream. An increase in the dispersion of energetic forms have different outcomes, one of which it would be a temporary reduction in the average temperature resultant for the mixing between Cold (Arctic) and warm (Mid-Latitude) masses of air as well as in altitude (SSW).

Subsequently, “temperature” is less reliable than looking at “work” seen even in the “mild” events.

In the framework presented throughout the line of research published in this blog (and researchgate) it has been considered “Climate” as being defined by the amount of energy free to do work. In other words, energy free to promote weather events. Accordingly, in my research I define Climate by the amount and state of energy in circulation, and Weather by the use of this energy.

Consequently, with the definition applied for Climate and Weather, my definition of Climate Drift is:

“the deviation from equilibrium of the conditions allowing the perpetuity of an established symbiotic relationship between biotic and none biotic components in a micro and macro ecosystem. This situation can be due to changes in any component of the ecosystem playing a synergistic effect over the rest. And the causes can be either a change in the magnitude of the already implemented forces in place, changes in the directionality or rates in the flows of energy pre-established OR/AND the impact suffered by the incorporation of new components/forces and energy sinks or sources in any part of the system interfering with the previously established order and balance.”

There have been some assessments showing major discrepancies between the line of research presented here and main stream scientific coverage. The assessments are about the concept of climate drift, the link between the Polar Vortex and tropospheric circulation, the role played by SST and the ENSO, the dynamics explaining abnormal Arctic Warming and sea ice cover,  the synergistic implications from the biotic component and the scientific methodology applied.

In the line of research presented in this blog it has been discussed the impact over energy flows derived from solar activity, land use and surface, atmospheric composition of GHGs and aerosols as well as the water cycle.

Based on the previous observations and assessments presented in this line of research, the state of the stratospheric circulation at both poles suggest that there is no need to have sudden warming process at stratospheric level in order to have a broken polar vortex. Such scenario was observed in October 2016 by the configuration of the polar vortex split at the NH without a stratospheric localised strong warming meanwhile the South pole was suffering a Sudden stratospheric warming without splitting the polar vortex.

But also, neither is required a broken polar Vortex in order to have displacements of cold polar masses of air into lower latitudes. Such configuration comes from the turbulent effect triggered at lower altitudes by warm masses of air moving towards the poles in latitude and altitude. A process of convection and advection moving warm masses of air towards the poles displacing cold masses of air in their way moving into Arctic circulation.

This behaviour can be explained by considering the thermal properties of the atmosphere as a system capable of carrying energy across higher latitudes and altitudes without dissipation and in enough concentration to affect the configuration of the polar vortex from the bottom up. Such capacity to keep momentum across latitudes and altitude conserving thermal energy can only be explained by an enhancement in the thermal properties of the atmosphere, which are directly related with its composition.

Throughout my line of research I suggest that there is one approach which is able to unify all events in a single principle. The incorporation of energy into the atmosphere is shaping the atmospheric dynamics we see affecting the behaviour of currents, storms, rain rates, lightning events, wind regimes and temperature variations.

The atmosphere might have trespassed a tipping point absorbing energy making to tremble its previous structural configuration in Latitude and Altitude.

The constant contact of warm masses of air from Low and Mid-Latitudes with those from polar latitudes has worn off the strength of the Polar Jet Stream. Such circumstance has allowed the intrusion of warm masses of air into higher latitudes and altitudes, increasing atmospheric turbulence. These convective intrusions are fuelled by the energy carried within water vapour, inducing the displacements  of other colder masses of air in altitude and latitude, increasing the mixing ratio between otherwise compartmentalized parts of the atmosphere.

Such circumstance has allowed the atmosphere to spread the energy carried by water vapour from Mid Latitudes into Polar Latitudes (Arctic latitudes), being able of holding more energy than before since it is not dissipated into their surroundings when moving across latitudes.

This scenario has induced a trans-Arctic interconnectivity between oceanic basins which has happened with and without the need for a strong sign of the ENSO. Therefore, this would suggest that exchange of masses of air between the Mid low latitudes with the Arctic, through the Polar Jet Stream, is the dominant driver in atmospheric circulation defining the behaviour of equatorial winds. But also, the configuration of the NH Polar Vortex.

Altogether the research here presented points to a new scenario in atmospheric dynamics in which the Arctic circulation, previously isolated from Subtropical influence by the Polar Jet Stream, has become open to be involved in the atmospheric dynamics for the Pacific and Atlantic basins. This new interconnection will affect the atmospheric dynamics around the whole North Hemisphere. But also, by being our atmosphere a close system, subsidiary, such alteration would affect dynamics at the Equator and due to symmetric compensation between Hemispheres, moreover into the Southern Hemisphere.

The Anthropogenic Link

As a biologist myself I find intriguing to see that our environment is predominately not described in biological terms.

Einstein made it very clear, our environment is a relative proportion of free energy and fixed energy in mass. There is one process in our system fixing E into mass, and one releasing E from mass. The “relative efficiency” of both processes is what is defining the behaviour of our thermodynamic environment.

There is an interference from human activities changing the composition and structure of the three phases of the environment:

  • solid; land cover and use affects albedo and changes in evapotranspiration rates due to biotic disruptions on wild population functionality,
  • the liquid phase through alterations over the water cycles, distribution of water bodies, and humidity of soils as well as affecting circulation patterns due to coastal deterioration and deformation, but also, indirectly due to alterations in the composition of the inert and biotic matter in the Oceans due to pollution and modifications in acidification and salinity related with atmospheric composition and thermal properties.
  • and gaseous phase due to alterations in the composition of the atmosphere from GHGs as well as aerosols, altogether affecting its thermodynamic behaviour.

The deviation from equilibrium of those conditions disrupt the perpetuation of an established symbiotic relationship between biotic and none biotic components in the micro and macro ecosystem.

The definitive link between human activities and atmospheric dynamics is under constant discussion since climatic developments are mainly approached from the field of physics.

However, the direct link between Anthropogenic activities and climatic developments are found in biological terms with thermodynamic implications:

Human activity has reduced CxHxOx compounds and increased free CxOx+HxOx.

Furthermore, anthropogenic activities release Energy from breaking structures (C-C) while biochemical processes assimilate energy fixing it into stable structures (CxHxOx).

Anthropogenic activity is simultaneously, releasing energy from a biochemically fixed state into the Planetary System’s Pool, at the same time that, it adds thermoactice compounds as CO2 and H2O. But furthermore, through this activity of constant transformational and processing, human activities are also debilitating the functionality of the biochemical processes capable of absorbing such perturbation, the endogenous ecosystems.

Einstein and his developments were mainly applied in physics due to the use that it was made of his work with the aim to manipulate energy in times of conflict, or to understand space. The equation is simple E=mc2. The language of physics has dominated the discussion over physical developments since then and it has been established as the logical translation of climatic developments. However, in the current times, the role of scientific understanding demands to move beyond the barriers of language, either between semantic cultural languages and between disciplines.

Being myself a Biologist involved in Atmospheric dynamics applying physics to explain such a complex subject as it is climatic evolution might seem like the tale of the child claiming that the Emperor has no clothes.

And yet, it seems to me evident that a thermodynamic system as it is our planet, can not scape from the most basic and powerful understanding of our contemporary scientific evolution. If E=MC2, and the anthropogenic activity is increasing the transformation of M into Energy in the system (from burning Mass from fossils and vegetable components, as well as by liberating other forms of energy such as gravimetric in Dams, Solar, transformation of raw materials, etc,) such transformation rate will move the balance in the thermodynamic behaviour of the whole system, and the rate of such deviation from equilibrium will be related with the speed at which the transformation rate between E/M is performed: M>(c)2




The main conclusion from my 4 years of researching synergistic interactions between all transformations seen over the Liquid, Gaseous and solid phases of our global Environment indicates that anthropogenic activity is forcing our environment into A System Becoming Dominated By Free Energy. (DOI: 10.13140/RG.2.2.18509.13289)

The biotic component of our environmental system is the only one capable of interacting against thermodynamic entropy, against instability. And for as long as Human activity can not replicate such mechanisms in equilibrium with the resources consumed, it might be time to think about domesticating Human Activities instead of following the obsession for Domesticating Natural Behaviour and Geoengineer our Weather. 


The analyses performed in my line of research describe a Climatic Drift, from pre-established atmospheric conditions strongly compartmentalised in Altitude and Latitude, towards a Climatic Regime characterised by an instability originated by patterns of Trans-latitudinal and Vertical mixing. An increase in atmospheric turbulence inducing sudden and extreme changes in atmospheric conditions generating weather events with abnormal properties for a particular location, throughout latitudes, longitudes and altitudes.

An increase in the amount of energy being in “free” state means that kinetic processes will increasingly dominate thermodynamic processes, inducing a transition in our Seasonal and Climatic regimes from being driven by Orbital Positioning to be driven by more erratic Kinetic processes.

The line of research presented in this blog describes a scenario where things happen for a reason, and where there are reasons for things to happen. No model offers that much. Meanwhile “reasons” explain probabilities, models use “probabilities” to let you figure out the reasons.

After leaving months, even years of time to expose my conclusions for public discussion and review, once those have no faced any criticism or arguments refuting their value, I create a pdf file and a DOI publishing them at my profile in Researchgate. In order to maintain their genuineness and legitimate innovative nature, I keep its original state so those can be compared with any copy made by any third party at any time.
