Weather and climate are related but different concepts. Weather refers to the short-term changes in the atmosphere, such as temperature, humidity, wind, and precipitation, that happen over a few hours, days, or weeks. Climate, on the other hand, is the average weather conditions in a place over a long period of time, typically averaged over 30 years. It includes statistics other than the average, such as the magnitudes of day-to-day or year-to-year variations. Climate is the expected frequency of specific states of the atmosphere, ocean, and land, including variables such as temperature, salinity, soil moisture, wind speed and direction, and current strength and direction.

To summarize:

• Weather refers to short-term changes in the atmosphere.
• Climate describes what the weather is like over a long period of time in a specific area.
• Weather is what you see outside on any particular day, while climate is the average of that weather over time and space.
• Climate encompasses the weather over different periods of time and also relates to mutual interactions between the components of the earth system.
