Weather and Climate
“Weather and Climate are essential concepts in understanding atmospheric conditions affecting Earth.”
Definitions
- Weather: The day-to-day state of the atmosphere at a particular place and time, including temperature, humidity, precipitation, wind, and visibility.
- Climate: The average weather conditions of a place over a long period (typically 30 years or more).

Factors Affecting Weather and Climate
- Latitude: Determines solar radiation intensity.
- Altitude: Temperature decreases with height.
- Distance from Sea: Coastal areas have moderate climate; inland areas experience extremes.
- Ocean Currents: Warm and cold currents affect temperature and rainfall.
- Topography: Mountains influence rainfall and wind patterns.
- Vegetation: Forests affect humidity and rainfall.
- Human Activities: Urbanization, pollution affect local climate.
Visual Comparison
Weather
- Short-term atmospheric conditions
- Temperature, humidity, precipitation
- Changes hourly or daily
- Unpredictable in long term
- Used for daily forecasts
Climate
- Long-term average weather
- Patterns over decades
- Relatively stable
- Determines ecosystems
- Used in planning and agriculture
