CWC holds meteorological expo

  • | Saturday | 24th March, 2018

The radiation recorder, sunshine recorder and shade ring, atop the CWC building, raised the curiosity of students. “The theme of this year’s World Meteorological Organisation (WMO) Day is ‘Weather-ready, Climate-smart’. Balloons with radiosonde instruments are released into the air to measure wind speed, wind direction, temperature and pressure at ‘standard levels’ like 1.5 km, 2.4 km and so on. A scientist explaining the instruments to students at the Cyclone Warning Centre on Friday. The variations in the maximum/minimum temperatures today and yesterday and the departure from the normal temperature are plotted in the ‘change chart’.

The objective of the expo is to create awareness among the public, especially students, and make them appreciate the processes involved in the collection and analysis of weather data and forecasting weather events accurately,” said GSLN Murthy, meteorologist at the CWC. Radiation sensors, mounted atop pillars on the terrace of the building, record diffused, terrestrial and ultraviolet (UV) radiation. The data logger on the first floor converts the analogue signals to digital. Balloons with radiosonde instruments are released into the air to measure wind speed, wind direction, temperature and pressure at ‘standard levels’ like 1.5 km, 2.4 km and so on. The readings are plotted on surface level and upper air charts and analysed to predict weather systems. The variations in the maximum/minimum temperatures today and yesterday and the departure from the normal temperature are plotted in the ‘change chart’. The radiation recorder, sunshine recorder and shade ring, atop the CWC building, raised the curiosity of students.
