Jet streams are fast flowing, narrow air currents. The main jet streams flow west to east around the globe.

Because of #climate collapse, the northern polar jet stream becomes more variable. A stratospheric polar vortex disruption is linked with extreme cold winter weather across parts of Asia and North America, including the Feb. 2021 North American cold wave.

Anyway, #AMOC (the main ocean current system in the Atlantic Ocean) currently offers 12°C to Ireland:

Climate change: Arctic warming linked to colder winters

A new study connects the heating of the Arctic region to extreme winter weather in the US.

Regional Climate Projections for Europe

Global climate change has different regional impacts; its effects are already noticeable today. Mankind will need to adapt to those future changes. To investigate possible regional climate changes in Europe in the 21. Century and to develop adaption strategies, regional climate simulations are performed. The Climate Service Center Germany (GERICS) is involved in the development of various models and methods to provide local climate change information. The simulated model results are stored at the DKRZ and can be downloaded from there through the ESGF (esgf-data.dkrz.de). DKRZ and GERICS have jointly produced animated visualizations showing the projected key changes in temperature and precipitation for Europe during the 21. Century.

In tropical forests, the most vital function of protected areas is limiting roads and road-related environmental disruption.

Climate Analogues for Temperate European Forests to Raise Silvicultural Evidence Using Twin Regions

Climate analogues provide forestry practice with empirical evidence of how forests are managed in “twin” regions, i.e., regions where the current climate is comparable to the expected future climate at a site of interest. As the twin regions and their silvicultural evidence change with each climate scenario and model, we focus our investigation on how the uncertainty in future climate affects tree species prevalence. We calculate the future climate from 2000 to 2100 for three ensemble variants of the mild (representative concentration pathway (RCP) 4.5) and hard (RCP 8.5) climate scenarios. We determine climatic distances between the future climate of our site of interest ‘Roth’ and the current climate in Europe, generating maps with twin regions from 2000 to 2100. From forest inventories in these twin regions we trace how the prevalence of 23 major tree species changes. We realize that it is not the ‘how’ but the ‘how fast’ species’ prevalence changes that differs between the scenario variants. We use this finding to develop a categorization of species groups that integrates the uncertainty in future climate. Twin regions provide further information on silvicultural practices, pest management, product chains etc.

Contemporary climatic analogs for 540 North American urban areas in the late 21st century - Nature Communications

It is challenging to communicate abstract future climate estimates. Here the authors utilized climate-analog mapping and they identified that North American urban areas’ climate by the 2080’s will become similar to the contemporary climate of locations hundreds of kilometers away and mainly to the south, while many urban areas will have no modern equivalent analogs under the RCP8.5 scenario.

The #subtropical climate has warm summers and mild winters. Temperatures vary according to height. The rains fall in winter in the north and are distributed throughout the year to the south. Societies have modified the landscape for livestock and agriculture.

Only the high #mountains of East #Africa have cold climates due to heights. It receives humid winds that produce important rains, especially in summer.

The desert winds are dry. In the Sahara the daily thermal amplitude reaches 80ºC.
