6-The Long Period Average (LPA) is the average rainfall received between 1971 and 2021 over a 50-year period. This equates to 87cm of rainfall on average.
7-The Pacific Ocean experiences La Nia weather patterns. This results in normal or above-average rainfall in India.
8-The term “El Nio” refers to the exceptional warming of surface waters in the eastern tropical Pacific Ocean. El Nio is Spanish for “the tiny boy.”
9-In 2022, the southwest monsoon is expected to be “normal.”

12-Western Disturbances are low-pressure systems embedded in westerlies, which flow from west to east.
13-Madden The Julian Oscillation (MJO) is a cloud, wind, and pressure disturbance that moves eastward at a speed of 4-8 metres per second. On average, the MJO travels around the world every 30-60 days. It can take up to 90 days at times.
14-According to a recent study published in Nature Climate Change and the IPCC’s Report (AR6), the Atlantic Meridional Overturning Circulation (AMOC) is losing its stability.

21- Every year, between 70 to 90 cyclonic systems form around the world. The wind spirals around a low-pressure area due to the Coriolis force.
22-Hurricane Ida recently made landfall in Louisiana, United States. It is a Category 4 storm, one of the most powerful storms to ever impact the United States.
23- A glacial lake is a body of water formed by glacier activity. They arise when a glacier erodes the terrain and then melts, filling the resulting depression.
24-The earthquake measuring 6.4 on the Richter Scale originated near Sonitpur, Tezpur, Assam, according to the National Centre of Seismology.
25-A landslide occurs when a pile of rock, rubble, or earth slides down a hill. Landslides include five types of slope movement: falls, topples, slides, spreads, and flows.
