Numerous observational studies have shown that the strength and position of the rear-flank downdraft (RFD) in supercell thunderstorms can vary substantially during the mesocyclone life cycle.
Linkages between boundary layer structure and evolution of the nocturnal low-level jet in the U.S. Southern Great Plains
Evapotranspiration (ET) is an important variable in the hydrologic cycle. As such, improved understanding of the spatial and temporal variability of ET is critical to weather and climate analysis and prediction, water management resources, agriculture, land-use and land-change projects, and ecological research.
Over the past century, the population of the world has become increasingly urbanized. As a result, cities have become larger and more densely populated than any time in history. This unprecedented growth and rapid modification of the surface has impacted the overlying boundary-layer of the atmosphere.
The prediction of a particular feature called a Tropopause Polar Vortex (TPV) has downstream implications on larger-scale atmospheric evolution and forecast skill. The TPV is a feature found in the Arctic that can persist for many days before ultimately exerting a major impact on weather forecasts over North America.

In this talk, Dr Fred Carr will discuss some of the reasons for U.S. skill in numerical weather prediction (NCEP) lagging behind and provide a potential path forward for the U.S. to match or surpass ECMWF accuracy.
