Anti-cyclone in North-east Asia

Role of Anti-cyclone in North-east Asia

New research has revealed a link between an increase in extreme summer heat events in Northeast Asia and the role of anticyclones in the region. Extreme heat events have increased across the world and are responsible for a large number of deaths and harming crops and livestock as well.

Nearly half of the magnitude of the 2018 extreme heat event across China and Japan was caused by anomalous anticyclones in Northeast Asia.

There are mainly 2 factors which make the extreme heat events more likely to occur over Northeast Asia.

Dynamic (anticyclone) and thermodynamic (mean temperature shifts to warmer states and increasing greenhouse gases) changes in the atmosphere.
Anticyclones similar to those in 2018 became more common and worse in recent decades (1991-2017) than the past (1958-1990).
The more extreme the heat event, the larger the contribution of the thermodynamic change will be.

Anti-Cyclone

An anticyclone is a large-scale circulation of winds around high atmospheric pressure, clockwise in the Northern Hemisphere, counterclockwise in the Southern Hemisphere.

It cause clear skies and high temperatures and responsible for settled weather conditions. Fog can also form overnight within a region of higher pressure.

It can form within warm core lows such as tropical cyclones, due to descending cool air from the backside of upper troughs such as polar highs, or from large scale sinking such as the subtropical ridge. The evolution of an anticyclone depends upon variables such as its size, intensity, and extent of moist convection, as well as the Coriolis force.
