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 ...
Weather map. A surface weather analysis for the United States on October 21, 2006. A weather map, also known as synoptic weather chart, displays various meteorological features across a particular area at a particular point in time and has various symbols which all have specific meanings. [1] Such maps have been in use since the mid-19th ...
Coastal ocean dynamics applications radar ( CODAR) is a type of portable, land-based, high frequency (HF) radar developed between 1973 and 1983 at NOAA 's Wave Propagation Laboratory in Boulder, Colorado. CODAR is a noninvasive system that can measure and map near-surface ocean currents in coastal waters. It is transportable and can produce ocean current maps on site in near real time ...
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 ...
In meteorology, the synoptic scale (also called the large scale or cyclonic scale) is a horizontal length scale of the order of 1,000 km (620 mi) or more. [1] This corresponds to a horizontal scale typical of mid-latitude depressions (e.g. extratropical cyclones ). Most high- and low-pressure areas seen on weather maps (such as surface weather analyses) are synoptic-scale systems, driven by ...
Cape Cod weather watchers have plenty to keep an eye on in the coming days, including a balmy Saturday and a possible coastal storm.
The history of surface weather analysis concerns the timetable of developments related to surface weather analysis. Initially a tool of study for the behavior of storms, surface weather analyses became a work in progress to explain current weather and as an aid for short term weather forecasting. Initial efforts to create surface weather ...
This map may save lives when there's a tornado threat. Meteorologist Craig "Ceecee" Croskery has spent the last two years identifying, verifying and logging buildings that he described as "almost ...
