GC-14 : Planetary Winds, Seasonal Winds & Local Winds Complete Lecture | Climatology |UPSC, PCS, SSC

Welcome to Ankur Srivastava Classes! In this comprehensive General Studies lecture, we cover the complete classification of wind systems in Climatology: Planetary Winds, Seasonal Winds, and Local Winds. This session is specially structured for aspirants preparing for UPSC CSE, State PCS, and SSC examinations. Understanding global wind patterns, seasonal reversals like monsoons, and regional local winds (both hot and cold) is essential for mastering Physical and Regional Geography. In this video, we break down these atmospheric mechanisms into clear, logical, and exam-oriented concepts. Key Topics Covered in This Lecture: Classification of Wind Systems: Primary (Planetary), Secondary (Seasonal/Periodic), and Tertiary (Local) winds. Planetary Winds (Primary Circulation): Trade Winds, Westerlies, and Polar Easterlies—their origin, global direction, and pressure belts. Seasonal Winds (Secondary Circulation): Land breeze and Sea breeze mechanics. Mountain and Valley breezes (Anabatic and Katabatic winds). Local Winds (Tertiary Circulation): Hot Local Winds: Loo (India), Fohn (Alps), Chinook (Rockies), Sirocco (Sahara/Mediterranean), Harmattan (Doctor Wind - West Africa), Khamsin. Cold Local Winds: Mistral (France/Alps), Bora (Adriatic Sea), Blizzard (Polar/North America), Pampero, Norther.
