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.

Scientists demonstrate that cloud seeding can generate snowfall

Ice-covered radar used in cloud-seeding experiment

Scientists have successfully used a combination of radars and snow gauges to measure the impact of cloud seeding on snowfall. The new research addresses decades of speculation about the effectiveness of artificial methods to increase precipitation, demonstrating unambiguously that cloud seeding can boost snowfall across a wide area if the atmospheric conditions are favorable.

The Annette Island Reserve is an island in Southeast Alaska and is home to the Metlakatla Indian Community (MIC), the only Indian reserve in Alaska. It comprises 87,000 acres which are critical fish and forestry resources to the community. The island locals rely on two primary lakes for drinking water and hydropower, Chester and Purple Lakes.

Countries bordering Lake Victoria, the largest freshwater body in Africa and the biggest inland fishery in the world, lack effective early warning systems to protect those who depend on them. According to the World Meteorological Organization (WMO), thousands of fishermen and small boat operators die on the lake each year; they get caught in deadly storms either because there is no weather warning, they do not receive the warning message, or the message is not presented clearly.

"The New York Power Authority (NYPA) and several research partners are moving into the final phase of a solar forecasting project, funded at $1.85 million, that will be able to predict solar energy generation to improve electric grid reliability and economic efficiency of power systems. The innovative solar study supports Governor Andrew M. Cuomo’s Green New Deal, which puts forth a plan to transition New York State to clean energy and sets the nation’s most ambitious goal for carbon-free power.
