The Basics of Weather

0

The term “weather” refers to the natural phenomena of weather, and it is a very broad category that includes climate conditions, the amount of precipitation, humidity, and clouds. This article will cover some of the basics of weather. After reading this article, you should be able to understand how each weather parameter affects your daily life. Once you understand how weather works, you’ll be able to interpret the weather forecast for any city. Then, you can make a more informed decision regarding where to go.

Temperature

The term “temperature” refers to the temperature of the air. Temperatures are measured with a thermometer and are reported by meteorologists in degrees Fahrenheit or Celsius. The United States uses the Fahrenheit system to measure temperatures while the rest of the world uses the Celsius scale. However, most scientists report temperatures in Celsius. Temperatures that are 70 degrees Fahrenheit or 32 degrees Fahrenheit may seem cool or warm after a couple days where it is 95 degrees. Likewise, weather that is cold at the poles is warmer near the Equator.

Precipitation

What is precipitation in weather? Simply put, precipitation is water that falls from clouds. It comes in many forms and is the main connection between the atmosphere and the earth’s water cycle. Water falls as rain, snow, hail, and sleet, and the amount that falls depends on the temperature of the air layer and the size of the particles. Some types of precipitation fall as a mixture of all these different substances.

Humidity

When talking about humidity and weather, it is important to understand two key terms: absolute humidity and relative moisture. The former refers to the amount of water vapor in the air as a function of temperature and pressure. Hotter air holds more water vapor than cooler air. The latter, on the other hand, refers to the ratio of the current absolute humidity to the highest possible absolute humidity – the highest humidity possible given the current air temperature. Most weather forecasters use relative humidity to describe the weather.

Clouds

If you are interested in the weather, you may have wondered how clouds form. Clouds are mass of water droplets or ice crystals in the atmosphere. The water vapor in the air condenses into clouds when the air becomes cool. As the water condenses, it expands into larger particles, which fall to the Earth as rain or snow. There are three main types of clouds, and each of them plays an important role in determining the weather and climate of the Earth.

Coriolis effect

The Coriolis force is the rotation of the Earth that causes objects to be deflected in opposite directions when they cross it. This phenomenon is responsible for large-scale weather patterns and has many practical applications. Here is a simple explanation of the Coriolis effect in weather:

Satellites

The first weather satellites launched in 1959 offered a variety of data and onboard sensors. Today’s satellites offer more sophisticated technology, with 16 wavelengths of analysis, each representing a specific sensor and target within the Earth’s atmosphere. The latest generation of weather satellites can provide an enormous amount of data, including sea states over oceans. These data can be crucial in the analysis of tropical disturbances. However, a significant problem with current weather satellite technology is the limited accuracy of their data.
