Monsoon Entered Bihar on Between June13 to 15

  

South-west monsoon has active over Kerala. Rain occurred at most places in Lakshadweep.

The rains, and relief, are on their way and would shower their blessings on the scorched state by next week,

 “The wind direction has changed from westerly to easterly in sub-Himalayan Bengal from the day before yesterday (Tuesday). This has sped up the flow of the eastern wing of the southwest monsoon towards north Bihar. It has already covered the entire sub-Himalayan Bengal. As a result of this, advancement of monsoon thunderstorms, accompanied by rainfall, has been observed in the northern parts of the state.”

He added: “On the basis of the prevailing conditions, we expect that monsoon would enter north Bihar between June 13 and 15.”

El Nino / La Niña-Southern Oscillation, is a quasiperiodic climate pattern that occurs across the tropical Pacific Ocean roughly every five years. The Southern Oscillation refers to variations in the temperature of the surface of the tropical eastern Pacific Ocean (warming and cooling known as El nino and La Niña respectively) and in air surface pressure in the tropical western Pacific. The two variations are coupled: the warm oceanic phase, El Niño, accompanies high air surface pressure in the western Pacific cause Rain fall, while the cold phase, La Niña, accompanies low air surface pressure in the western Pacific cause no Rain. Mechanisms that cause the oscillation remain under study.
The extremes of this climate pattern's oscillations, El Niño and La Niña, cause extreme weather (such as floods and droughts) in many regions of the world. Developing countries dependent upon agriculture and fishing, particularly those bordering the Pacific Ocean, are the most affected. In popular usage, the El Niño-Southern Oscillation is often called just "El Niño". El Niño is Spanish for "the little boy" and refers to the Christ child, because periodic warming in the Pacific near South America is usually noticed around Christmas.This year El nino is weak so chances of Monsoon will come very soon

Last year, monsoon had entered the state on June 15.

Abdul Sattar, assistant professor of meteorology, Rajendra Agriculture University, Pusa, echoed the Met department’s observation. “Monsoon is progressing at a very high speed in sub-Himalayan Bengal. It is expected that monsoon would enter the northeastern region of Bihar in four to seven days. Going by the present calculations, Kishanganj would be the first district to be hit by the monsoon.”

Sattar claimed that favourable dynamics in weather conditions over the Bay of Bengal and in the sub-Himalayan region on the mainland have led to speeding up of monsoon in the region.

Earlier, weather scientists had claimed that the arrival of monsoon in Bihar was likely to be delayed by five days from the normal date of arrival due to rise of 0.5°C in the surface temperature of the Pacific Ocean.
