Cold Wave

Texas was facing a disaster – but the natural hazard was only the trigger. The failure of power grids is a technological consequence: one that can be measured, quantified and ultimately reduced.
Keeping the Texas grid disconnected from the rest of the country means it won’t fall under federal regulations. But it also means Texas can’t borrow power from other states when its power infrastructure fails, as it did in February 2021.
This study provides an overview of subseasonal predictability for case studies of some of the most prominent extreme events across the globe using the ECMWF S2S prediction system.
A new study looks at environmental impact over five decades on 10 economic sectors in 48 U.S. states, and concludes that cold and wet weather compared to historical norms have greater negative economic effects than hot and dry weather in certain sectors.
Researchers from the U.S. Department of Energy’s (DOE) Argonne National Laboratory studied the 2021 Texas cold wave from another angle: how Texas and other parts of the country can improve power system planning and electricity market operations.
A new study challenges a commonly accepted explanation that a "sudden stratospheric warming" caused the unusually cold weather over the U.S. early last year, a view which was widely reported in the media and discussed among scientists at the time.

Cold waves are an overlooked disaster, with few humanitarian agencies acting to tackle these impacts. Consultations indicated that much more could be done to reduce the vulnerability of those most at risk – including acting ahead of a forecast cold wave.
India has got its first climate vulnerability atlas, based on 14 extreme weather events and the risks they pose to the local population, livelihoods and economy of each district.

Spatio-temporal mapping of climatic and biological disaster outbreak in India has been undertaken using historical data and scientific tools to explore options to support for relief, recovery, resilience, and adaptation.
As the temperatures were forecast to be below the trigger levels, a test simulation of anticipatory actions was conducted to support the rural communities expected to experience the most serious impacts from this extreme cold wave.
