Monsoon advance to central and north India delayed

This is for the second consecutive week, IMD warned about a break in the monsoon.

The southwest monsoon's advance into remaining parts of peninsular India and rest of the country has been delayed further in the absence of a critical atmospheric push from the ocean.

The India Meteorological Department (IMD) on Monday said further progress of southwest monsoon is not likely in the next five to six days due to the prevalence of a weak monsoon pattern.

This is for the second consecutive week, IMD warned about a break in the monsoon. On June 13, the MeT agency issued the first alert on the stagnation in monsoon's march to central, north, northwest and parts of peninsular India that has not received much rain so far.

Much to the disappointment of the parched and sultry north, central and eastern India, the IMD now forecast continuation of a lull till at least till June 23-24.

This has happened because of an unfavourable weather condition known as Madden-Julian Oscillation that can delay monsoon onset, result in a break in activity or end a monsoon season prematurely.

"We don't have convection clouds because of an unfavourable MJO. Large-scale flow patterns are not there. There would be no revival of monsoon for the next 5-6 days," IMD scientist M Mahapatra told DH.

MJO is a large-scale atmospheric disturbance that impacts the monsoon shower in the tropics where the rainfall is generally associated with thunderstorms and winds are predominantly easterly. 

Periods of moderate to strong MJO are often followed by little or no activity.

The last phase of MJO that boosted the summer monsoon passed the Indian Ocean last week and the next MJO cycle is expected around June 25, when the weathermen expects a revival of the monsoon.

Till then, the heatwave in eastern and parts of central India will continue.
