OPC pressure forecast valid at 48 hours. Marine weather forecasting is the process by which mariners and meteorological organizations attempt to forecast future weather conditions over the Earth 's oceans. Mariners have had rules of thumb regarding the navigation around tropical cyclones for many years, dividing a storm into halves and sailing ...

In about 350 BC, Aristotle described weather patterns in Meteorologica. [3] Later, Theophrastus compiled a book on weather forecasting, called the Book of Signs. [4] Chinese weather prediction lore extends at least as far back as 300 BC, [5] which was also around the same time ancient Indian astronomers developed weather-prediction methods. [6]
The history of numerical weather prediction began in the 1920s through the efforts of Lewis Fry Richardson, who used procedures originally developed by Vilhelm Bjerknes [1] to produce by hand a six-hour forecast for the state of the atmosphere over two points in central Europe, taking at least six weeks to do so. [2] [1] [3] It was not until ...
Using a hydrostatic variation of Bjerknes's primitive equations, [2] Richardson produced by hand a 6-hour forecast for the state of the atmosphere over two points in central Europe, taking at least six weeks to do so. [3] His forecast calculated that the change in surface pressure would be 145 millibars (4.3 inHg), an unrealistic value ...
Map of regions covered by the 122 Weather Forecast Offices. 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.
