Introduction

Monsoon trough is the low pressure belt extending from West to East. It is the remnant of ITCZ that moved to South Asia with northern solistic.

Main Body

Factors for northward shifting:

(i) Weakening of the Tej streams (subtropical) caused by phenomena like arctic amplification.

(ii) Increasing temperature of the auroral plains as cited by IMD in last century that creates conducive situation for northward water.

(iii) Warming of Bay of Bengal region & its physical proximity to North east region – caused by global Warming & climate change.

(iv) Increasing temperature in the Himalayan region & foothills.

Implications:

(i) Increased rainfall in NE regions.

(ii) Negative for NW India with reduced rainfallshift continuity effect already [illegible].

(iii) Increased evapotranspiration thus moisture index.

(iv) Extreme weather events like cloudbursts, Thru, shifting pressure system need tackled with better preparedness (agroeconomic planning) & fulfilling climate goals of Paris cleaf.
