Revision Notes – Weather, Climate,Crops & Means of Transport of India (Designed for quick recall – JKSSB Accounts Assistant (Finance) GK)
1. WEATHER & CLIMATE OF INDIA
1.1. Definition
- Weather – Day‑to‑day atmospheric conditions (temperature, humidity, rainfall, wind).
- Climate – Long‑term average of weather (typically 30‑year mean).
1.2. Factors Influencing Indian Climate
| Factor | Effect on Climate | Example |
|---|---|---|
| Latitude | Tropical (0‑23.5° N) → high solar insolation; subtropical north → cooler winters | South India hot year‑round; Himalayas cold |
| Altitude | Temperature drops ~6.5 °C per 1000 m | Shimla cooler than Delhi |
| Pressure & Wind Systems | Shift of ITCZ, subtropical westerlies, jet streams | Summer monsoon inflow from SW |
| Distance from Sea | Maritime moderates extremes; continental interior shows large diurnal/annual range | Coastal Mumbai vs. inland Nagpur |
| Topography | Blocks or channels winds; creates rain‑shadow | Western Ghats cause heavy rain on windward side; leeward Deccan plateau dry |
| Ocean Currents | Warm currents raise coastal temps; cold currents reduce | Somali Current influences Arabian Sea; Bay of Bengal warm pool fuels monsoon |
1.3. Seasons (IMD Classification)
| Season | Months | Main Features |
|---|---|---|
| Winter | Dec‑Feb | Cool, dry; Western Disturbances bring light rain to NW; occasional snowfall in Himalayas |
| Pre‑monsoon (Summer) | Mar‑May | Rising temps; Loo (hot, dry winds) in NW; pre‑monsoon showers (mango showers) in South & East |
| South‑West Monsoon | Jun‑Sep | Main rainy season; ~75% of annual rainfall; onset over Kerala ~1 Jun; withdrawal starts NW Sep |
| Post‑monsoon (Autumn) | Oct‑Nov | Retreating monsoon; cyclones in Bay of Bengal; clear skies, pleasant weather |
1.4. Climatic Regions (Köppen‑Geiger simplified)
| Code | Region (Approx.) | Characteristics |
|---|---|---|
| Aw | Tropical Savanna – most of Peninsular India, Gujarat, Rajasthan (eastern parts) | Hot summers, distinct dry winter, moderate monsoon rain |
| Am | Tropical Monsoon – West Coast, Northeast, parts of Odisha | Very high rainfall (>2000 mm), short dry season |
| Cwa | Humid Subtropical – Gangetic plain, Punjab, Haryana, Uttar Pradesh, Bihar, West Bengal | Hot summer, mild winter, adequate monsoon rainfall |
| Cfb | Oceanic – Himalayan foothills (Sikkim, Arunachal) | Mild temperatures, rainfall throughout year |
| ET | Tundra – High Himalayas (above ~3500 m) | Permanently cold, snow cover |
| BSh/BWh | Hot Semi‑arid/Arid – Rajasthan, Gujarat, parts of Haryana & Punjab | Low rainfall (<500 mm), high temperature extremes |
1.5. Monsoon Mechanics – Quick Mnemonics
- “S.W. Monsoon = Summer Winds” – Southwest winds bring rain in summer (Jun‑Sep).
- “N.E. Monsoon = Winter Winds” – Northeast winds bring rain to SE coast (Oct‑Dec).
- “ITCZ dances north in summer, south in winter” – Inter‑Tropical Convergence Zone shifts with sun’s apparent movement.
1.6. Key Highlights (Exam‑Ready)
- India receives ≈ 1170 mm average annual rainfall; 70% occurs during SW monsoon.
- Highest rainfall: Mawsynram (Meghalaya) ~11,873 mm/yr.
- Lowest rainfall: Leh (Ladakh) ~100 mm/yr.
- Temperature extremes:
- Hottest: Phalodi (Rajasthan) 51.0 °C (May 2016).
- Coldest: Dras (Jammu & Kashmir) –45 °C (Jan).
- Western Disturbances cause winter precipitation in NW India; crucial for Rabi crops.
- El Niño → weaker monsoon, deficient rainfall; La Niña → stronger monsoon, floods.

Final Tip for the Exam – Read the question stem carefully – many GK items mix two sub‑topics (e.g., “Which state is the largest producer of both wheat and sugarcane?” → Answer: Uttar Pradesh).
- Use the tables for rapid elimination – match the state with the crop or transport mode.
- Remember the share percentages – they often appear in assertion‑reason questions.
- Revise the mnemonics just before the paper; they act as mental cues to recall sequences and classifications.
Good luck – you’ve got this! 🚀
