636 high-resolution dropsondes reveal four types of atmospheric boundary layer over the Antarctic, including well-mixed and convective types.Read More »Atmospheric Sciences
A new measurement capability can detect the polarization of the radio frequency wave of lightning sources, which reveals different forms of lightning breakdown processes.Read More »Atmospheric Sciences
Radar data show an afternoon precipitation maximum in the equatorial Indian Ocean in addition to the nocturnal maximum; this occurs under light surface winds and suppressed large-scale convection.Read More »Atmospheric Sciences
For the first time, simultaneous measurements of upper atmosphere temperatures over altitudes 80 to 110 kilometers have been made by two complementary lidar techniques.Read More »Atmospheric Sciences
Polar vortices play a central role in coupling the atmosphere from the ground to the middle atmosphere. New satellite diagnostics describe mesospheric polar vortices and coupling to lower altitudes.Read More »Atmospheric Sciences
Measurements made during a field campaign in Idaho indicate that the speed of winds 2 meters above Earth’s surface determines the type of turbulence present in nighttime inversions.Read More »Atmospheric Sciences
Emission from a ship’s engine gives clues to how much light-absorbing molecules may build up on and above snow and sea ice. Such emissions are likely to increase as more ships venture into the Arctic.Read More »Climate Change
An analysis of historical modeling outputs is improving our understanding of the relationships between different types of seasonal forecasting skills.Read More »Atmospheric Sciences
