Weather and Climate
Weather is the state of the atmosphere that describes the degree to which it is, for example, hot or cold, wet or dry, calm or stormy, clear or cloudy. Most weather events occur in the troposphere, the lowest layer of the planet’s atmosphere, just below the stratosphere. Weather refers to daily temperature, precipitation, and other atmospheric conditions, while climate is the term used for the average of atmospheric conditions over more extended periods. Used unqualified, “weather” generally means the weather of the Earth.

Weather is affected by differences in air pressure, temperature, and humidity between places. These differences can occur due to the Sun’s angle at any point varying with latitude. The strong temperature contrast between polar and tropical air results in the largest-scale atmospheric circulations: Hadley cell, Ferrel cell, polar cell, and jet stream. Mid-latitude weather systems, such as non-tropical cyclones, are caused by jet flow instability. Because the Earth’s axis is tilted relative to the orbital plane, sunlight comes in at different angles at different times of the year. At the Earth’s surface, temperatures are usually in the range of 40 °C per year. Over the millennia, changes on Earth have changed.

Climate is the long-term weather pattern in a region, often averaging more than 30 years. More precisely, it is the average variability of meteorological variables over time, spanning from months to millions of years. Some commonly measured meteorological variables are temperature, humidity, atmospheric pressure, wind, and precipitation. In a broader sense, the climate is the state of the components of the climate system and the interactions between them, including the atmosphere, hydrosphere, cryosphere, lithosphere, and biosphere. A place’s climate is affected by latitude/longitude, terrain, altitude, land use, and nearby bodies of water and currents.
