Factors of Weather

Meteorology or atmospheric science was first established in Aristotle era. It was him who created the term "meteorology" in the article titled "Meteorology". Meteorology is not just atmospheric science but also includes research on physics and geography. When mentioning that someone is studying meteorology, they especially referred to atmospheric science and its "weather". As we know, "weather" is the state of air at a certain place and time.

The elements that contribute to the weather of the area (actually the global weather) are the changes of the Earth's season, marine mode, windwards, ice of the Arctic Ocean, and the shape of the jet (see below). These factors may lead to extreme weather in various parts of the northern hemisphere. In such places, snow accumulates frequently, but in other places you get warmth beyond the timing. The season we experience is the result of the rotation of the tilt axis of the earth around the sun. During the winter of North America, our hemisphere is leaning away from the sun, lighting the sun at our angle and lowering the temperature. Climate change does not affect the inclination of the earth, but it may affect many other factors that affect the weather of the US winter, such as Arctic Ocean Ice, Polar Jet, Polar Vortex and El Niño.

The transition period of the El Niño or La Niña phenomenon can also be an important factor influencing the global weather of the teleconnection. Critical events are measured by Trans-NiñoIndex (TNI) called Trans-Niño. Examples of short-term climates affected in North America include Northwestern precipitation and US tornado activities. Southern oscillation is the atmospheric component of the El Niño phenomenon. This component is atmospheric pressure fluctuation between the eastern tropical and western Pacific oceans. The intensity of southern vibration is measured by the southern vibration index (SOI). SOI is calculated based on the variation in pressure difference between Tahiti (Pacific) and Darwin (Indian Ocean) in Australia.

El Nino - We tend to experience the El Nino phenomenon directly in the US, but Southern Oscillation is probably the most famous teleconnection, but the weather is warming and the weather effect is caused by atmospheric change. In the El Niño phenomenon, the action of the atmosphere is so-called southern oscillation, a periodic change of the tropical Pacific barometric pressure of Indonesia. This pressure change will cause us to think about El Nino weather. As researching the teleconnection, researchers get colder in the winter in North America as the Arctic Circle (including Alaska and Eastern Siberia) gets warmer - changes in temperature are closely related to changes in atmospheric patterns I realized that I was there. The authors found that this change in circumstances also leads to a decrease in precipitation in the central and southern part of the United States.
