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
