Students of Sriprakash Vidyaniketan,Payakaraopeta visited Meteorological Observatory located in Tuni. Sri ch.Apparao, Scientific assistant explained about Self Recording Rain Guage (S.R.R.G) how rain fall recorded and also about Humidity and temperature record through Hygrometer ( records humidity) Thermometer (temperature) Barometer (atmospheric pressure)Wind vane(wind direction) anemometer(wind speed). Students are enlightened about how cyclones occur in our Indian ocean and names are given for them.How changes happen from low pressure to high pressure,depression, deep depression, cyclone, Severe cyclone, very severe cyclone and super cyclones and their formations.
