On the need for volumetric radar data when issuing severe thunderstorm and tornado by David A. Imy, Kevin J. Pence, Charles A. Doswell Iii - Doswell III, On 28 February , a violent tornado (F4) struck Jones COl/nty in southeast Mississippi. The Lemon technique is a method used by meteorologists using weather radar to determine the relative strength of thunderstorm cells in a vertically sheared environment. It is named for Leslie R. Lemon, the co-creator of the current conceptual model of a supercell. The Lemon technique is largely a continuation of work by Keith A. Browning, who first identified and named the supercell. Leslie R. Lemon (born Janu ) is an American meteorologist bridging research and forecasting with expertise in weather radar, particular regarding severe convective is, along with Charles A. Doswell III, a seminal contributor to the modern conception of the supercell which was first identified by Keith Browning, and he developed the Lemon technique to estimate updraft Alma mater: University of Oklahoma.

At values greater than g m-3, virtually every thunderstorm produced severe-criteria hail, regardless of the actual VIL or the thunderstorm height. At values below g m-3, very few. Abstract. Radar is a very important tool in identification of severe thunderstorm hazards. Recent surveys suggest that as many as 80% of the National Weather Service severe thunderstorm warnings are based on radar (Lowden, ).Cited by: Severe thunderstorm warnings are given as either a broad-based warning, covering expected impact in a weather reporting area, or as a detailed warning, when a thunderstorm is within weather-watch radar range and includes a map depicting any existing thunderstorms and the forecast direction of movement for up to 60 minutes. Abstract. This review is concerned with electrification and lightning in severe weather. Based on substantial evidence that the electrical processes active in ordinary (nonsevere) thunderstorms are also present in severe storms, the initial discussion here is focused on ordinary by:

What we do: NSSL is a world leader in developing weather radar technologies for improved observations, predictions and warnings of high-impact weather including tornadoes, severe thunderstorms and flash floods. NSSL has developed severe weather warning applications and decision support systems that combine data from radar and other sensors to make the forecasters job easier. New severe thunderstorm radar identification techniques and warning criteria: a preliminary reportCited by: When a thunderstorm meets one or more of these minimum criteria, the local NWS forecast office will issue a severe thunderstorm or tornado warning accordingly. Before you depart, you can see any current warnings on the local NWS forecast office's website. They are depicted as red (tornado) or yellow (severe thunderstorm) polygons on the NEXRAD.
