Why is This Happening? Understanding the Weather Pattern
The current weather changes are driven by a trough extending from central Odisha to Vidarbha combined with an anticyclonic circulation over the Bay of Bengal at lower tropospheric levels. These systems result in the following:
- Increased moisture influx from the Bay of Bengal, leading to cloud formation and rainfall.
- Unstable atmospheric conditions that create thunderstorms and lightning.
- Wind disturbances that cause gusty winds and sudden downpours.
According to IMD forecasts, these factors will contribute to severe weather conditions in the region.
