NEXRAD or Nexrad (Next-Generation Radar) is a network of 159 high-resolution S-band Doppler weather radars operated by the National Weather Service (NWS), an agency of the National Oceanic and Atmospheric Administration (NOAA) within the United States Department of Commerce, the Federal Aviation Administration (FAA) within the Department of Transportation, and the U.S. Air Force within the ...
Mesoscale meteorology. Mesoscale meteorology is the study of weather systems and processes at scales smaller than synoptic-scale systems but larger than microscale and storm-scale. Horizontal dimensions generally range from around 5 kilometres (3 mi) to several hundred kilometers. Examples of mesoscale weather systems are sea breezes, squall ...
e. Meteorology is a branch of the atmospheric sciences (which include atmospheric chemistry and physics) with a major focus on weather forecasting. The study of meteorology dates back millennia, though significant progress in meteorology did not begin until the 18th century. The 19th century saw modest progress in the field after weather ...
In a weather map as the one to the right, a col is a region where the position of highs (H) and lows (L) produces a convergence or divergence of the airflow; this includes 2 juxtaposed highs and 2 juxtaposed lows. This pattern packs isotherms and moisture: warm air is advected from the South (TI) while cold air comes from the North (PI) at the ...
Atmospheric sounding or atmospheric profiling is a measurement of vertical distribution of physical properties of the atmospheric column such as pressure, temperature, wind speed and wind direction (thus deriving wind shear ), liquid water content, ozone concentration, pollution, and other properties. Such measurements are performed in a ...
Convective inhibition. Convective inhibition ( CIN or CINH) [1] is a numerical measure in meteorology that indicates the amount of energy that will prevent an air parcel from rising from the surface to the level of free convection . CIN is the amount of energy required to overcome the negatively buoyant energy the environment exerts on an air ...
A. ab-polar current. Any air current moving away from either the North Pole or the South Pole. advection. The horizontal transport of some property of the atmosphere or ocean, such as thermal energy, humidity, or salinity. In the context of meteorology, the related term convection generally refers to vertical transport.
The Cape Cod National Seashore and Ducks Unlimited partnered on a project to remove the dead vegetation from a roughly 125-acre area. An additional 25 acres in the nearby High Toss Road area was ...
