Biological Productivity, Amazonia and Atmospheric Circulation. (by Diego Fdez-Sevilla)


(updated 9 Jan 2015) Biological Productivity, Amazonia and Atmospheric Circulation. (by Diego Fdez-Sevilla)

In this blog I have already discussed the uncertainty that it brings into any Climate models and Atmospheric Circulation understanding to leave uncharacterised the relevance of Biological Productivity and the impact of inducing profound changes over it around the globe.

Two mayor synergies have been identified between Biological productivity and Atmospheric Circulation. One is the production of compounds in the form of aerosols increasing drop nuclei activity in the atmosphere, and thus, enabling the development of more clouds. The other one is the increase of Atmospheric Water Vapour as the result of evapotranspiration.

Here I want to share an image from 22 Dec 2014 which just represents such type of synergy. On the left the image shows the extension of the Amazonia (Amazon river and rainforest). On the right the image shows the atmospheric  Total Precipitable Water over the Amazonia and the currents of air at 850 hPa atmospheric level.

In order to update this post and increase the material helping to visualize the synergistic interaction between Plant Biological Productivity and Atmospheric Circulation I share some images showing the continuity of the previous one, this time from the 9th of January 2015. The images show the Total Precipitable Water over the Amazonia at 850 hPa (Left) with the currents of air associated. The image on the right shows the bifurcation of the current of air at Jet stream level 250 hPa over the Amazonia.

It has been discussed previously in this blog how Oceans, as well as the Sun’s activity, are key features in our climate and weather system. For some, these two features are strong enough to overcome any alterations due to Land Use and Cover (discussion found here). And yet, I believe that these images are just an example which supports the need for giving strong relevance to consider changes in Land Use and Cover as key factors when assessing their potential impact over atmospheric circulation.

The “Influence of continentality” and “Biological productivity” over weather events and global circulation are still features to be characterised. For further discussion you can also check the posts in this blog under those categories and also those under “Solar activity” and “Environmental Resilience“.

In addition, I leave you here an interesting article.

Mapping Carbon in the Amazon

Mapping the Amazon’s stores of carbon could go a long way to helping protect the forests, though. This study is the first one to produce high-resolution images of the carbon stocks of tropical vegetation on a national scale. The resolution and accuracy of these carbon maps are so precise that landowners of individual pieces of property can compare their land to their neighbors in regards to carbon content.

There is also hope that this mapping technique could be used to help scientists determine how use of the land affects rainfall patterns in the Amazon. Recent research has shown that, in the last 14 years, rainfall in the Amazon is declining as much as 25 percent, partly because of the lack of vegetation. These remote sensing mapping techniques could be applied to other parts of the globe as well in order to chart the carbon stores of different forests and help keep the Earth well.

Bachelor in General Biology, Masters degree "Licenciado" in Environmental Sciences (2001, Spain). PhD in Aerobiology (2007, UK). Lived, acquired training and worked in Spain, UK, Germany and Poland. I have shared the outcome from my work previous to 2013 as scientific speaker in events held in those countries as well as in Switzerland and Finland. After 12 years performing research and working in institutions linked with environmental research and management, in 2013 I found myself in a period of transition searching for a new position or funding to support my own line of research. In the current competitive scenario, in order to demonstrate my capacities instead of just moving my cv waiting for my next opportunity to arrive, I decided to invest my energy and time in opening my own line of research sharing it in this blog. In March 2017 the budget reserved for this project has ended and its weekly basis time frame discontinued until new forms of economic and/or institutional support are incorporated into the project. The value of the data and the original nature of the research presented in this platform and at LinkedIn has proved to be worthy of consideration by the scientific community as well as for publication in scientific journals. However, without a position as member of an institution, it becomes very challenging to be published. I hope that this handicap do not overshadow the value of my achievements and that the Intellectual Property Rights generated with the license of attribution attached are respected and considered by the scientist involved in similar lines of research. **Any comment and feedback aimed to be constructive is welcome as well as any approach exploring professional opportunities to be part of.** In this blog I publish pieces of research focused on addressing relevant environmental questions. Furthermore, I try to break the barrier that academic publications very often offer isolating scientific findings from the general public. In that way I address those topics which I am familiar with, thanks to my training in environmental research, making them available throughout my posts. (see "Framework and Timeline" for a complete index). At this moment, 2017, I am living in Spain with no affiliation attachments. Free to relocate geographically worldwide. If you feel that I could be a contribution to your institution, team and projects don´t hesitate in contact me at d.fdezsevilla (at) gmail.com or consult my profile at LinkedIn, ResearchGate and Academia.edu.
