  • What are the Characteristics of the Troposphere?

    What are the Characteristics of the Troposphere?

    The characteristics of the Troposphere: The atmosphere has a multi-layered structure consisting of the following basic layers. Troposphere, Stratosphere, Mesosphere, Ionosphere, and Exosphere. The word troposphere derives from the Greek word Tropo and it means turbulence or mixing. This is the lowermost layer of the atmosphere and is known as the troposphere and is the most important lowest layer of earth surface because almost all the weather events ( e.g fog, cloud, due, frost, hailstorm, storms, cloud-thunder, lightning, etc.) occur in this lowest layer. Thus the troposphere is of the utmost significance for all life forms including man because these are concentrated in the lowermost portion of the atmosphere.

    Here explains; What are the Characteristics of the Troposphere? Read and learn.

    Temperature decreases with increasing height at the average rate of 6.50 C per 1000m (1 kilometer) Which is called a normal lapse rate. The height of the troposphere changes from the equator towards the poles (decreases) and from one season of a year to the other season(increases during summer while decreases during winter). The average height of the troposphere is about 16km over the equator and 6km over the poles. The upper limits of the troposphere are called TROPOPAUSE.

    What is the Importance of the Troposphere?

    The troposphere provides several important benefits: it holds nearly all of the water vapor in the Earth’s atmosphere, regulates temperature, and produces weather. The troposphere forms the lowest level of the Earth’s atmosphere, extending down to the surface of the Earth. This lowest layer also features the heaviest weight of all earth surface atmosphere layers, comprising approximately 75 percent of the total atmospheric weight.

    The troposphere varies in thickness and height around the world. At its highest point, the troposphere extends 12 miles into the air. At its lowest point, this layer reaches 4 miles above sea level. Regardless of height, the troposphere facilitates temperature regulation and cloud formation. It contains the highest temperatures closer to its base; these warm temperatures help the troposphere retain water vapor, which releases in the form of precipitation.

    The troposphere also serves as the starting point for the Earth’s water cycle. This process begins when the sun pulls water into the atmosphere through evaporation. Water then cools and condenses, forming clouds. Clouds store water particles, which are released in the form of rain, sleet, or snow depending on the time of year and region. The troposphere also traps gases, such as carbon dioxide and nitrogen. Excess accumulation of these substances creates environmental problems, such as smog and air pollution.

    Characteristics of the Troposphere:

    The following Characteristics below are:

    • Most of the weather phenomena take place in this lowest layer. The troposphere contains almost all the water vapor and most of the dust.
    • This layer subject to intense mixing due to both horizontal and vertical mixing.
    • Temperature decreases with height at an average rate of 10C per 167m of height above sea level. This calls the normal lapse rate.
    • The troposphere extends up to a height of about 18km at the equator and declines gradually to a height of 8km at the poles.
    • The upper limit of the troposphere calls the tropopause. The temperature stops decreasing in it. It may be as low as -580C.

    All-weather changes occur in the troposphere. Since it contains most of the water vapor, clouds form in this layer of earth surface.

    Frequently Asked Questions (FAQs)
