K-index (meteorology) Lightning. The K-Index or George's Index is a measure of thunderstorm potential in meteorology. According to the National Weather Service, the index harnesses measurements such as "vertical temperature lapse rate, moisture content of the lower atmosphere, and the vertical extent of the moist layer."

College of DuPage is a public community college with its main campus in Glen Ellyn, Illinois. [3] The college also owns and operates satellite campuses in Addison, Carol Stream, Naperville and Westmont. [4] [5] With more than 20,000 students, the College of DuPage is the second largest provider of undergraduate education in Illinois, after ...
In April 2013, persistent heavy rains caused widespread flooding, primarily impacting the Midwestern and Great Lakes regions. In a span of two days on April 17 and 18, heavy rainfall associated with a slow-moving storm system caused widespread flooding across rivers and areas, where rainfall amounts over 8 inches (200 mm) caused rivers to swell and crest, including the Mississippi River and ...
Gregory Stanley Forbes (born August 22, 1950) is The Weather Channel's long-time severe weather expert and has a significant research background in the areas of severe convective storms and tornadoes. Born and raised near Latrobe, Pennsylvania, Forbes earned a B.S. degree in meteorology at Pennsylvania State University (PSU).
Weather. Cloud physics is the study of the physical processes that lead to the formation, growth and precipitation of atmospheric clouds. These aerosols are found in the troposphere, stratosphere, and mesosphere, which collectively make up the greatest part of the homosphere. Clouds consist of microscopic droplets of liquid water (warm clouds ...
Capping inversion (cap); Center for Analysis and Prediction of Storms (CAPS); Center for Severe Weather Research (CSWR); Chaser convention – Originally it referred to serendipitous meeting of chasers in the field akin to "chaser convergence", but now it mostly refers to the National Storm Chasers Convention Archived 2013-06-22 at the Wayback Machine held annually in the Denver, Colorado area.
Isentropic analysis is a technique in meteorology to find the vertical and horizontal motion of airmasses during an adiabatic process above the planetary boundary layer. The change of state of air parcels following isentropic surfaces does not involve exchange of heat with the environment. [1] Such an analysis can also evaluate the airmass ...
The Weather Prediction Center ( WPC ), located in College Park, Maryland, is one of nine service centers under the umbrella of the National Centers for Environmental Prediction (NCEP), a part of the National Weather Service (NWS), which in turn is part of the National Oceanic and Atmospheric Administration (NOAA) of the U.S. Government.
