The 3.5-day virtual course looks at the science of QPF for intense precipitation events.The course will focus on rainfall that triggers rapid hydrologic responses in drainage basins, with an emphasis on flash flood producing storms. The material will focus mostly on warm-season convective events, but also include cool season mesoscale processes that lead to intense rainfall and snowmelt. Subtopics will explore interpretation of atmospheric anomalies, understanding NWP guidance, spatial verification methods, identifying and forecasting warm rain processes, forecasting storm initiation and propagation, orographics, remote sensing tool, situational awareness, and societal impacts.Questions of precipitation intensity, duration, and area will be discussed in the context of some recent significant events.
