Closer home, polar vortex and polar jet stream find nearest possible expression in alternating wet spells and dry cold over North India, as modulated by western disturbances. These disturbances originate in the Mediterranean, and are sub-tropic perturbations ...
Obtaining high-rate data from the mesosphere-lower thermosphere region is a chal- lenge, and continuous ground observations of the mesospheric wind and temperature in the vicinity of the stratospheric polar vortex edge are still rare. Furthermore, sudden strato- spheric warming (SSW) manifestations...
MODIS hotspot data from 1 June 2002 to 31 August 2021 were used to identify fire history, fire activity during the summer from 1 June to 31 August, and distribution in the Arctic region. An active fire period is defined here as consecutive fire days when the number of daily HSs is greate...
for very active fires. The fire–weather analysis approach described in this paper has shown that future large-scale fire outbreaks are predictable. Keywords: wildland fire;hotspot;fire weather;warm air mass;cut-off low;cut-off high;large westerly meandering;climate change...
Under a warmer climate in the future, more severe fire weather, more area burned, more ignitions, and a longer fire season are expected [3]. An impending shift to a temperature-driven global fire regime in the 21st century is creating an unprecedentedly fire-prone environment [4]. In recen...
