Temperatures are increasing continuously in most states across the country. In North India, whether it is UP, Bihar or states like Rajasthan and Madhya Pradesh, the heat has started wreaking havoc in the month of March itself. The Meteorological Department (IMD) has predicted ‘loo’ ie ‘heat wave’ conditions in many states.
According to the Meteorological Department, heat wave conditions are going to prevail in Himachal Pradesh, Delhi, Gujarat, Rajasthan, Madhya Pradesh, Maharashtra. The question arises that why the situation like ‘Loo’ has started happening in the month of March only. Also, the effect of heat wave is being seen not only in India but also in other countries, where the weather is generally pleasant in the month of March.
‘Loo’ runs in the months of May-June
If we talk about India, then it starts getting hot from April and there is severe heat in May-June. ‘Loo’ means ‘heat wave’ also moves in these months, but this sequence has changed for the last few years. This time the heat wave has started from March itself. Even the poles of the earth are not untouched by this effect. The weather patterns at the poles are also changing rapidly. Heat is increasing in both the Arctic and Antarctic. Experts believe that the heat has increased simultaneously at both the poles of the Earth.
This time the process of becoming ‘Lu’ started early.
A ‘heat wave’ begins when high pressure builds up in the atmosphere and moves warm air towards the land. This effect is caused by heat rising from the ocean, creating an ‘amplification loop’. The high pressure system falling below the surface expands vertically, causing rapid changes in the activities of other weather systems. It also loosens the cover of wind and clouds, making the air more rigid. This is the reason that a ‘heat wave’ ie ‘Loo’ blows over an area for several days or for much longer. This time the process has started happening faster. Therefore, the effect of heat is being seen in March itself.
heat rising at the poles too
Walt Meyer, a scientist at Australia’s National Snow and Ice Data Center, says that this situation is unpredictable. According to the report, the temperature at Concordia Station on the Antarctic Plateau is usually minus 50 degrees in March, but in recent days, the temperature was recorded at minus 20 degrees Celsius. Some parts of Antarctica are warmer than 70 °C (40 °C) on average. Some parts of the Arctic region are 50 °C (38 °C) warmer than average. Berkeley Earth’s senior scientist Dr. Robert Rohde tweeted about this that the remote research station of ‘Dome C’ has recorded a temperature of about 40 degrees Celsius above normal. Last year this figure was more than 20 degrees Celsius.
so fast changing weather
Scientist Dr. Rohde says that the conditions present on Antarctica are due to an atmospheric river or large scale accumulation of water vapor in the sky, when the effect of ‘Loo’ means ‘heat wave’ is visible early. This could be a major reason for the rise in temperature. He believes that this is a strange phenomenon completely different from our expectations. Due to the Atmosphere River (atmospheric river), the heat has also increased at the poles. This can be understood as a warning condition. Associate Professor Alex Sen Gupta of the University of New South Wales says that the temperature of Antarctica has increased due to strong hot winds.
