🌀 What is a Monsoon? ☀️ April–May:
• Seasonal reversal of winds 🌬️ • 🌞 Sun shines directly over Tropic of Cancer
• Brings distinct wet (rainy) & dry seasons ☀️🌧️ • 🔥 Northern India heats up → Low Pressure Zone
• Driven by 🌡️ differential heating of land and sea • 🌊 Indian Ocean remains cool → High Pressure Zone

• Pulls SE trade winds → deflect → SW Monsoon Winds • Hits windward side →
Deccan Plateau (leeward side) = 🌵 dry

• Central India:
💨 Role of Jet Streams • Flows via Narmada & Tapi valleys
• 🧭 Westerly Jet Stream: • 💧 Rain in Chhattisgarh, Madhya Pradesh,
• Withdraws from Northern India during summer Chotanagpur (~15 cm)

• Shifts north of Himalayas → 🔔 signals monsoon onset • Northwest India:
