Alaska thunderstorms may triple with climate change

Clouds and lightning.

The number of thunderstorms in Alaska may triple by later this century because of climate change, increasing the risks of widespread flash flooding, landslides, and lightning-induced wildfires.

Responding to extreme heat conditions during the COVID-19 pandemic could place many vulnerable populations at further risk during the warm summer months when many people leave their houses to escape the heat and visit cooling centers and other public spaces. People's vulnerability is likely to vary over time and space, shifting with the extent of exposure to extreme heat, differences in policy and community response, and disease pressure from COVID-19.

Small Unmanned Aerial Vehicles (UAVs), or drones, are emerging as the next major economic sector of society, as well as a new tool for sensing the lower atmosphere. However, these small autonomous aircraft are much more vulnerable to winds, turbulence and icing than manned aircraft. NCAR studies continue to drive predictive capabilities toward the microscale.
