Indian States have been gradually registering a withdrawal of Spring.

Reason behind this situation

• Spring is the period of relatively benign weather between the winter of January and the scorching summers of April.
• As the Earth orbits the Sun, sunlight strikes the surface at varying angles because of the planet’s tilt. This creates seasons. However, temperatures in February have become warmer, leading to a missing spring season.
• The warming of winter in southern India and the lack of rainfall in the north in winter due to an aberration in the pattern of Western Disturbances and the jet stream, winds that originate in the Mediterranean and bring moisture to north India during winter.
