The National Weather Service operates 122 weather forecast offices. [1] [2] Each weather forecast office (WFO or NWSFO) has a geographic area of responsibility, also known as a county warning area, for issuing local public, marine, aviation, fire, and hydrology forecasts. They also issue severe weather warnings, gather weather observations, and ...
The Citizen Weather Observer Program is a program to collect surface weather observations from thousands of privately operated weather stations, into the FindU database, and forward it to the Meteorological Assimilation Data Ingest System (MADIS Archived 2009-03-12 at the Wayback Machine), operated by the National Oceanic and Atmospheric Administration (NOAA).
Map of sea areas and coastal weather stations referred to in the Shipping Forecast. The stations are listed in the order they are read in the forecast, the numbers in brackets refer to the map on the right. Weather reports included in the forecasts are issued at 2300 local time for the late broadcast and 0400 for the early one, although reports ...
A surface weather analysis for the United States on October 21, 2006. By that time, Tropical Storm Paul was active (Paul later became a hurricane). Surface weather analysis is a special type of weather map that provides a view of weather elements over a geographical area at a specified time based on information from ground-based weather stations.
It was a backbone of the U.S. climatological observation network and remains an important network in providing long-term observations of particular locations. The Cooperative Weather Observer network consists of manual observations of only a few variables and consists of daily summaries rather than being continuous (i.e. real-time).
A surface weather analysis is a special type of weather map that provides a view of weather elements over a geographical area at a specified time based on information from ground-based weather stations. [2] Weather maps are created by plotting or tracing the values of relevant quantities such as sea level pressure, temperature, and cloud cover ...
Weather reconnaissance aircraft, such as this WP-3D Orion, provide data that is then used in numerical weather forecasts.. The atmosphere is a fluid.As such, the idea of numerical weather prediction is to sample the state of the fluid at a given time and use the equations of fluid dynamics and thermodynamics to estimate the state of the fluid at some time in the future.
The world's first televised weather forecasts, including the use of weather maps, were experimentally broadcast by the BBC in November 1936. [31] This was brought into practice in 1949, after World War II. [31] George Cowling gave the first weather forecast while being televised in front of the map in 1954.
