Wind circulation refers to the movement of air in the atmosphere around the world. When the air cools, it falls to the ground and flows back to the Equator, where it warms up again. The pattern repeats as the now-warm air rises again. This whole process of wind circulation is known as Convection.
The air movement from a high-pressure area to a low-pressure area is called wind. Winds can be extensively isolated into three sorts:
- Permanent winds: These winds constantly blow throughout the year, e.g., Trade winds, westerlies, and easterlies
- Seasonal winds: These winds change their path with change of season, e.g., monsoon winds
- Local winds: These winds blow during particular periods of the day or year in a particular direction. e.g., sea breeze, land breeze, Loo, etc.
Weather and Climate
Weather refers to the events that take place in our environment like rainstorm, snowfall, or a Sunny day. When a cumulative look at the weather over a span of time is viewed, it is known as climate. Weather changes from time to time, it has a temporary nature, whereas Climate describes a general weather condition of a region considering a period of time.
Wind plays an important role in weather changes because it transports warm air, cold air, and moisture in the atmosphere, causing the weather to change.
- The level of hotness and chilliness of the air is known as temperature
- An important factor that influences the distribution of temperature is insolation
- Insolation is the approaching sun-oriented energy captured by the Earth. The measure of insolation diminishes from the Equator to the Poles. Consequently, temperature diminishes similarly.
- Air pressure is characterized as the strain applied by the heaviness of air on the Earth’s surface
- As we go up the layers of the environment, the tension falls quickly. The gaseous tension is the most elevated adrift level and diminishes with tallness
- In regions having a lower temperature, the air is cold. It is accordingly weighty. Accordingly, high strain is related to clear and radiant skies.
Moisture in the air
- Dampness noticeable all around is known as moistness. When the air is loaded with water fumes, we consider it a damp day as the air gets hotter, its ability to hold the water fumes increases. Thus, it turns out to be increasingly sticky
- At the point when water vanishes from land and distinctive water bodies, it becomes a water fume. At the point when the water fume rises, it begins cooling. The water fume gathers, causing the development of drops of water. Precipitation that pours down to the Earth in a fluid-structure is called downpour.
Based on instrument, there are three kinds of precipitation:
- Convectional rainfall
- Orographic rainfall
- Cyclonic rainfall
The average weather condition of a place for a long period of time represents the climatic condition of that area. The amount of insolation received by the area determines its climatic condition and the temperature. Variation in temperature between two areas creates a difference of air pressure, which gives rise to winds. Wind is the large-scale movement of air and other gasses above the surface. It originates when air moves from a high pressure area to a low pressure area, and it is divided into three categories: permanent winds, seasonal Winds, and local winds. Water carried by the wind is a measure of moisture in the air, and this moist air leads to precipitation. Permanent winds encircle the whole of the earth in tropical areas it is known as trade winds, in temperate areas it is called westerlies and above temperate areas it is known as polar easterlies.
