Two colors of weather patterns have been seen in the country in the month of March. According to the Indian Meteorological Department (IMD), the first two weeks of March have been warm, while the weather has been cooler in the latter two weeks. According to the data, in the last 73 years, the last two weeks of March have been among the ten coldest weeks. The rain in March has also increased the difficulty.
The March average maximum temperature in Delhi was 0.31 degrees Celsius below normal. This is the 34th time in Delhi that the weather has been cold in March. The first two weeks of March in Delhi were 2.1 and 1.9 degrees Celsius warmer than normal. At the same time, the next two weeks were 2.8 and 2.5 ° C below normal, which broke the record of 73 years.
Fluctuations in mercury of states
Data related to the weather of 10 out of 30 states and union territories of the country has been studied. Of this, six states Assam, Punjab, Tripura, Kerala, Manipur and Mizoram are such where the summer was 0.5 degrees above normal. Whereas in Sikkim, Jammu and Kashmir, Meghalaya, Telangana and Maharashtra, the mercury went down by 1.1 degree to 4.99 degree Celsius.
coldest march since 1951
According to the IMD, the country’s average maximum temperature till March 29 was 30.5 degrees. According to the gridded data set, the mean temperature from 1981 to 2010 is 0.96 °C lower. March temperature has been the coldest since 1951. There was nothing in the department’s forecast regarding the weather in March that the mercury would fall like this in March.
unexpected weather
The IMD forecast on February 28 that March would be above normal in most parts of the country. In the first week, the mercury remained above normal by 1.1 degrees. Two weeks later, the temperature across the country came down by 1.3 degrees Celsius. For the week ending March 21 and March 28, the mercury dropped by 3.5 and 2.3 degrees Celsius, respectively, keeping the weather cool.
Five main reasons why this happens
1. Fall in mercury due to simultaneous activation of two Western Disturbances.
2. High level of circulation in Rajasthan and coastal areas.
3. Wind at a speed of 120 to 200 km in the upper troposphere.
4. Increase in moisture level from Bay of Bengal and Arabian Sea.
In 5. March, mercury fell in many areas of the country due to unseasonal rains.
India’s role in climate change is 4.8 percent
India’s contribution to the climate crisis is 4.8 per cent of the global average temperature. And America’s share is 17.3 percent. China is at number three in the list with 12.3 per cent. According to the report published in Nature Journal, the maximum emission of gases like carbon dioxide, methane, nitrous oxide is happening in the atmosphere. In an attempt to accelerate the economy, these gases are becoming a means of increasing the temperature of the world.
three gases are responsible
According to a joint report by Britain’s Tyndall Center for Climate Research and other organizations, three gases are a major factor in increasing the heat in the atmosphere. By 2021, emissions of these gases have increased the global temperature by 0.28, China by 0.20, Russia by 0.10, Brazil by 0.08 and India by 0.05 degree Celsius. Similarly, Japan, Canada and Britain are contributing 0.03 to 0.05 degree Celsius to the global temperature.
The role of developed countries is important
According to the research paper, the role of developed countries is important in the direction of increase in global temperature after industrial revolution. To prevent global temperature rise, work is going on around the world to cut carbon emissions. Despite this, there is no significant difference between the emission of gases and the increase in global temperature. Experts estimate that these three gases will be fatal to the environment as well as to health.
