Weather vs Climate

Weather forecast is the assessment of what the weather will be like over a short period of time. Forecasts are made on the basis of fluid mechanics, combining factors such as air, wind and water... Climate is the study of meteorological variables over a long period of time (30 years by convention). Several parameters distinguish weather from climate:
- The time scale: weather forecasts are made over a week, whereas climate trends are thought out over a decade or even a century.
- The geographical scale: weather forecasts are local, whereas climate forecasts look at trends over an entire region, or even the planet. In short: weather forecasts look at day-to-day fluctuations, whereas climate forecasts look at all these fluctuations over a long period of time.
Here’s a fun hint: You've been a calm, reserved person for 30 years (climate) and you get all worked up for 72 hours (weather)!
