Lake-effect snow is produced during cooler atmospheric conditions when a cold air mass moves across long expanses of warmer lake water. The lower layer of air, heated by the lake water, picks up water vapor from the lake and rises through colder air. The vapor then freezes and is deposited on the leeward (downwind) shores.
The National Center for Supercomputing Applications (NCSA) is a state-federal partnership to develop and deploy national-scale cyberinfrastructure that advances research, science and engineering based in the United States.

Joshua Michael Aaron Ryder Wurman is an American atmospheric scientist and inventor noted for tornado, tropical cyclone, and weather radar research, the invention of DOW and bistatic radar multiple-Doppler networks.
Harold Edward Brooks is an American meteorologist whose research is concentrated on severe convective storms and tornadoes, particularly severe weather climatology, as well as weather forecasting.
The Verification of the Origins of Rotation in Tornadoes Experiment are field experiments that study tornadoes. VORTEX1 was the first time scientists completely researched the entire evolution of a tornado with an array of instrumentation, enabling a greater understanding of the processes involved with tornadogenesis. A violent tornado near Union City, Oklahoma was documented in its entirety by chasers of the Tornado Intercept Project (TIP) in 1973. Their visual observations led to advancement in understanding of tornado structure and life cycles.
