Advancement in Measuring Weather Elements
In recent days, weather stations use weather balloons, aircraft and ships to carry the instruments for measuring the temperature, pressure, humidity in the lower atmosphere. Weather radars are used to locate precipitation, type, intensity.
Radiosonde (an instrument carried by balloon or other means to various levels of the atmosphere and transmitting measurements by radio) is an instrument used to measure the vertical profiles of temperature, dew point and winds. It estimates the wind direction, velocity based on radar tracking.
Weather satellites help in providing all weather information accurately. Some of the important weather satellites are: METSAT-1/ KALPANA -1, OCEANSAT-2, INSAT -3D, SCATSAT-1
