DISTINCTION
Momentary vs. Average
- Weather: The momentary state of the atmosphere at a specific place and time (e.g., cloudy, windy today).
- Climate: The average of weather conditions over a long period (usually more than 30-50 years).
- Key Elements: Both share the same elements: Temperature, Pressure, Wind, Humidity, and Precipitation.
Prism Memory Hook

- Summer: Churu (Rajasthan) may record 50°C, while Tawang (Arunachal) records only 19°C on the same day.
- Winter: Drass (Ladakh) may drop to -45°C, while Thiruvananthapuram remains at 22°C.
