Syllabus: GS-I Subject: Geography Topic: Indian Climate, Issue: Missing Spring Season in India
Context: Climate trends indicated a disappearance of spring, traditionally occurring between winter and summer.
Study Findings:
- February stands out as a month of significant warming across all regions analysed.
- Contrast between January (cooling or slight warming) and February (strong warming) suggests abrupt transitions from cooler to warmer conditions.
Causes:
- Alterations in the pattern of Western Disturbances and the jet stream are cited as causes for these changes.
| Western disturbances are extratropical storms that originate in the Mediterranean region and bring rain and snow to the northwestern parts of the Indian subcontinent.
Jet streams are fast-moving, narrow air currents high up in the tropopause, the boundary between the troposphere and the stratosphere. Generally blow from west to east (westerly winds).
