Feb 1, 2011 · The local weather that impacts our daily lives results from large global patterns in the atmosphere caused by the interactions of solar radiation, Earth's large ocean, diverse landscapes, and motion in space.
- Polar vortex. The menacing phrase "polar vortex" is a relatively new term for winter weather forecasting, but meteorologists have understood it as a concept for decades.
- Atmospheric (barometric) pressure. Humans inhabit the very bottom of the Earth's atmosphere and everything above creates atmospheric pressure. High-pressure systems form when downward pressure creates a clockwise air rotation, unlike low-pressure systems, which generate counter-clockwise rotation.
- Inch of mercury. Inch of mercury is a unit used to measure air pressure. It represents the amount of pressure the atmosphere places on a one-inch column of mercury under standard gravity at zero degrees Celsius.
- Ball lightning. Lightning in its traditional form is frightening and deadly on its own, but ball lightning is scary even in the context of instant electrocution from the heavens.
Weather Systems Cloud patterns indicate the presence of weather systems, which produce most of the weather we are familiar with: rain, heat waves, cold snaps, humidity, and cloudiness. Weather systems are simply the movement of warm and cold air across the globe.

- Weather and Climate
The weather events happening in an area are controlled by changes in air pressure. Air pressure is caused by the weight of the huge numbers of air molecules that make up the atmosphere. Typically, when air pressure is high their skies are clear and blue. The high pressure causes air to flow down and fan out when it gets near the ground, preventing ...
Meteorologists develop local or regional weather forecasts including predictions for several days into the future. The best forecasts take into account the weather events that are happening over a broad region. Knowing where storms are now can help forecasters predict where storms will be tomorrow and the next day. Technology, such as weather satel...
The average weather pattern in a place over several decades is called climate. Different regions have different regional climates. For example, the climate of Antarctica is quite different than the climate of a tropical island. Global climate refers to the average of all regional climates. As global climate changes, weather patterns are expected to...
Mar 9, 2016 · Weather is what you experience when you step outside on any given day. In other words, it is the state of the atmosphere at a particular location over the short-term. Climate is the average of the weather patterns in a location over a longer period of time, usually 30 years or more.
Jun 26, 2024 · To understand weather, meteorologists study atmospheric patterns. The most familiar atmospheric pattern that drives weather and climate is convection, the process of warmer air rising, and colder, denser air sinking. Convection results in a transfer of energy, heat, and moisture—the basic building blocks of weather.
