New climate model developed by Russian and German scientists

Kazan, Russia (SPX) Mar 29, 2018

This is the kinetic energy of winds at 5 km altitude in December-February (Aeolus calculations).

Professor Aleksey Eliseev, Chief Research Associate at Kazan University's Near Space Research Lab, comments, "To find solutions for some tasks in climate research, we need calculations for hundreds, thousands, or even millions of years. Such tasks are, for example, ice age periodization. Another group of tasks that requires huge longitudinal calculations is climate forecasting, a type of research where we don't have definitive information about coefficients of used models.

"If we use models of the general circulation of atmosphere, then required calculations can take up months or years with the use of the most advanced modern computers. To accelerate research, scientists use simplified models - the so-called climate models of intermediate complexity. In Russia, the only such model has been created by the Institute of Atmospheric Physics.

"Our team, comprising employees of Potsdam Institute for Climate Impact Research, Moscow State University, Kazan Federal University, and the Institute of Atmospheric Physics, is working on one such model. We called it the Potsdam Earth System Model."

Currently, one of the components of POEM, called Aeolus, is ready for use. Two parts of the model, for large-scale zonal-mean winds and planetary waves, have been designed by Dr. Eliseev. He has also partaken in the creation of automatic tuning process for model parameters.

Cilmatologists render drought predictions that help avert famine
Santa Barbara CA (SPX) Mar 19, 2018
Last year, 81 million people worldwide experienced severe food insecurity. About 80 percent of them live in Africa. While much of that food insecurity relates to civil war and violence in places like South Sudan and Nigeria, a good portion also stems from a sequence of five severe droughts that began in Ethiopia in 2015 and spread across parts of the continent in the ensuing three years. Climatologists at UC Santa Barbara's Climate Hazards Group (CHG) have been studying the relationships bet ... read more
