Artificial ground weather stations and automatic ground weather stations all over the country regularly observe and record these meteorological data every day, and send them to the Meteorological Data Center of China Meteorological Bureau after summarizing them. Reporting meteorological observation records to the meteorological data center, therefore, it is an important supplement to the meteorological station network.
Meteorological radar (Doppler radar) determines the position and characteristics of the target through the reflection of radar waves. The weather radar emits radio waves, judges the precipitation intensity and its change through the echo, and judges the distance from the rain and snow clouds through the time of receiving the echo.
Meteorological satellites are always detecting and forecasting atmospheric changes, making all-day and all-weather observations, quickly collecting and processing data and information, feeding them back to ground receiving stations, drawing images and determining directions.
Weather forecast The development history of weather forecast.
Numerical value is the language of science. Weather forecast is inseparable from the quantitative observation of atmospheric motion by instruments. We can set the invention and application of meteorological instruments as the start time of early weather forecast.
/kloc-in the 5th century, the west invented the pressure plate anemometer, which can quantitatively measure the velocity (energy) of atmospheric motion for the first time. 17-18th century, scientists have successively invented various instruments for quantitatively measuring weather phenomena, marking the beginning of a new development period for the detection means of meteorological scientific research. The British physicist Hooke (1635- 1703) invented the hygrometer.
1606, Galileo invented the thermometer. 1639, Galileo's disciple BenedettoCastelli invented the rain gauge. 1644, Torricelli invented the barometer. 1774, Kurt invented the hygrometer. /kloc-in the middle of the 0/8th century, people began to try high-altitude exploration.
