Where to Find Real Weather Models


How accurate is modern meteorology?

The Short Answer: A seven-day forecast can accurately predict the weather about 80 percent of the time and a five-day forecast can accurately predict the weather approximately 90 percent of the time. However, a 10-day—or longer—forecast is only right about half the time.

What does an H on a weather map indicate?

High pressure systems A high pressure system is an area of high pressure relative to its surroundings. On the chart, it appears with an ‘H’ with the number indicating the pressure. In the southern hemisphere, the wind flows anticlockwise around and away from a high pressure system.

What are the symbols for the fronts?

Symbols are used on surface weather maps to indicate the characteristics or type of front.

  • A stationary front line is indicated by blue triangles on one side of the line alternating with red semi-circles on the opposite side of the line.
  • A cold front is a front that is moving in the direction of the warmer air.

How do you identify fronts?

To locate a front on a surface map, look for the following:

  1. sharp temperature changes over relatively short distances,
  2. changes in the moisture content of the air (dew point),
  3. shifts in wind direction,
  4. low pressure troughs and pressure changes, and.
  5. clouds and precipitation patterns.

What computer models do meteorologists use?

Supercomputers NOAA’s Weather and Climate Operational Supercomputer System (WCOSS) is the backbone of modern forecasting. With 5.78 petaflop computing capacity it can process quadrillions of calculations per second.

What model does National Weather Service use?

Global Forecasting System (GFS)
The National Weather Service’s current Global Forecasting System (GFS) has been the foundation of our suite of weather models for over 30 years.

Who makes the current forecast for North America?

Surface Weather… Statistical Models… Hazard Assmt… Publications… Comments… This current Forecast for North America is produced by the Hydrometeorological Prediction Center of the National Centers for Environmental Prediction. It is normally updated at about 7am US Eastern time.

Where do NOAA’s current weather data come from?

Current obserations from NOAA’s geostationary satellites. Snow analyses for water equivalent, depth, snowpack temperature, and snow melt. Upper air observations from radiosonde stations in North America, Pacific Islands, and Caribbean.

What are the five main features of weather data?

Temperature, sky conditions, visibility, precipitation type and accumulation, wind speed and direction, and more as reported by surface observation stations.
