Satellites have revolutionized weather forecasting by providing accurate, real-time data that meteorologists use to predict and track weather patterns. The use of satellites in weather forecasting has significantly improved the accuracy of forecasts, allowing people to prepare for extreme weather events and mitigate their impact.
The Evolution of Satellite Technology in Weather Forecasting
The first satellite used for weather forecasting was launched in 1960, but it wasn't until the 1980s that satellite technology advanced enough to provide reliable data for meteorologists. Today, there are hundreds of satellites orbiting the earth that collect data on everything from temperature and humidity to wind speed and cloud cover.
Satellite technology has come a long way since its inception. Early satellites were only capable of transmitting low-resolution images, but today's satellites can capture high-definition imagery in real-time. This means that meteorologists can see weather patterns as they develop rather than relying on outdated information.
Types of Satellites Used in Weather Forecasting
There are several types of satellites used in weather forecasting:
- Geostationary Satellites: These are placed at a fixed point above the earth's equator and remain stationary relative to the surface below. They provide continuous coverage over a specific region.
- Polar Orbiting Satellites: These orbit over both poles at an altitude between 500-800 km above earth's surface providing global coverage.
- Deep Space Climate Observatory (DSCOVR): It is located about one million miles away from Earth towards Sun-Earth L1 Lagrange point which provides full disc solar image daily along with space environment monitoring Each type has its benefits when it comes to gathering different types of information about the atmosphere.
Advantages and Disadvantages
The use of satellite technology has numerous advantages when it comes to predicting extreme weather events such as hurricanes, tornadoes or typhoons:
