• For India it was the hottest month since 1901, recording the highest monthly average maximum (day) temperature (29. 5 degrees Celsius) in 122 years.
  • The India Meteorological Department on Tuesday signalled bitter days ahead with a forecast of hotter than normal summer in many parts of the country during the March-May period.
  • Among different regions, February recorded the highest monthly averaged day temperature in northwest India, followed by central India, since 1901 when the IMD started keeping weather records.
  • In fact in northwest India, the monthly average temperature in February was 3. 4 degrees Celsius higher than the normal while in Central India, the monthly average tem-perature was 2. 05 degrees C above the normal. Chennai recorded 19. 5 degrees Celsius.
  • As far as the summer season is concerned, most parts of northeast, east, central and certain areas of northwest India, including Delhi NCR, are expected to face “above-normal” maximum(day) temperatures during the period when even number of heatwave days may be more than last year.
  • Southern peninsula and most of Maharashtra are, however, expected to face normal summer temperatures.
  • The IMD, in its seasonal outlook, said, “Enhanced probability of occurrence of heatwave during March to May season is likely over many regions of central and adjoining northwest India.”
  • Though the entire globe is living in an era of climate change and global warming, the attribution (direct link to climate change) is normally a matter of diagnosis.
  • In case of extreme situations, the agriculture ministry is ready with extension services and support to farmers in case of extreme weather events, there is no report of adverse impact of temperatures on the farming operations so far.

Engine powering rocket’s cryogenic upper stage test

  • The flight acceptance hot-test of the CE-20 cryogenic engine that will power the cryogenic upper stage (CUS) of the GSLV-Mk3 or LVM3 launch vehicle for the Chandrayaan-3 mission was successfully conducted on February 24 at its propulsion complex.
  • The hot test was carried out for a planned duration of 25 seconds at the high-altitude test facility.
  • All the propulsion parameters during the test were found satisfactory and closely matched with predictions.
  • The cryogenic engine will be further integrated with the propellant tanks, stage structures and associated fluid lines to realise the fully integrated flight cryogenic stage.
  • The Chandrayaan-3 mission, which Isro is targeting this year, has been gaining pace in the past few weeks.
  • Key Lander Test Too, the Chan-drayaan-3 lander successfully underwent EMI/EMC (Electro-Magnetic Interference/ Electro-Magnetic Compatibility) test.
  • The test is conducted for satellite missions to ensure the functionality of the satellite subsystems in the space environment and their compatibility with the expected electromagnetic levels.
  • This test is a major milestone in the realisation of the satellites.
  • Reiterating that the Chandrayaan-3 mission has three major modules — the Propulsion module, Lander module, and Rover — Isro said, the mission’s complexity calls for establishing radio-frequency (RF) communication links between the modules.
