Description

The Global Analysis and Prediction System, GLAPS, produces maps for several weather parameters over a large global domain. There are seven GLAPS products available for Science On a Sphere®. It is important for meteorologists to know the current conditions, not only in their local area, but also globally. A computer model is used to create a first guess as to what the map should look like, and then observations are added to enhance the map. The observations come from Doppler radars, satellites, wind and temperature profilers, radiometric profilers, as well as aircraft. GLAPS is such a powerful tool because of its ability to consolidate observations from so many different sources. The GLAPS datasets are available in real-time, updating hourly, and include the data for the past week.

Every real-time GLAPS dataset all updates hourly. GLAPS Sea Surface / Ground Temperature is a map of sea surface and ground temp in degrees Fahrenheit. Red/yellow represent the hottest areas while purple/white the coldest. Both the sea and the land are warmer in the lower latitudes no matter what season it is, thanks to the angle of incidence of the sun's shortwave radiation influx. Warm ocean currents are also visible on the east coasts of continents, i.e. Kuroshio (Japan), Agulhas (Africa), Gulf Stream (US). Where as the poles stay purple and white throughout the year.The colorbar for temperature is below.

Notable Features

  • Color variation shows temperature in Fahrenheit; red/yellow shows the hottest regions where as purple/white the coldest
  • The equatorial regions are warmer due to direct solar input and the poles are coldest due to indirect or no solar input depending on the season
  • Warm water ocean currents are visible on the east coasts of continents, i.e. Kuroshio (Japan), Agulhas (Africa), Gulf Stream (US)
