      There is also a type of warm wind which occurs in Mountains when moisture containing winds travels up in the wind facing side of mountains, Reaching at the high point (due to low temperature) they condense and precipitate leaving the moisture in the wind facing side. While when they cross the mountain they become dry. On the leeward side of the mountain, they descend and gets warm(When the air parcel or wind descend due to increase in atmospheric pressure the air parcel compress and gets warm this process is called the adiabatic process.) This warm air causes the snow in the leeward side of the mountain to melt.

    • @RATHNAM-jb7rx
      @RATHNAM-jb7rx Месяц назад

      Since the number of air molecules above a surface decreases with height, pressure likewise decreases with height. Most of the atmosphere's molecules are held close to the earth's surface by gravity. Because of this, air pressure decreases rapidly at first, then more slowly at higher levels.

      @sangpriyagautam1658 3 года назад +3

      When we say a gas exerts pressure, then we are implying the gas molecules are hitting the walls of the container. The velocity of gas molecules increases on increasing the temperature. How? Imagine a corn jumps on heating and becomes pop corn. Now, consider the gas molecules with high velocity as vehicles on roads with high speeds...there are more chances of collisions 😬because there is randomness in the gas molecules. As the no. Of Collisions increased, the pressure will increase. If you need technical back up for the explanation then follow the gas rules of chemistry PV =nRT.

    Sir, on earth surface, temperature and pressure are inversely proportional, if one increases, then the other decreases. Eg. High temperature during summers, led to low pressure_as the air get warmed up & rises.
    And, altitude-wise, temp. & pressure are directly proportional.
    With due respect, I found your statement confusing, as they are not always directly proportional. That's why, want to clear my doubt.

      "In the earths atmosphere, pressure, which is related to the number of molecules per unit volume, decreases exponentially with altitude. Thus, if a parcel of air from the surface rises (because of wind flowing up the side of a mountain, for example), it undergoes an expansion, from higher to lower pressure. When you allow air to expand, it cools. This phenomenon is familiar to everyone--stick your finger on the valve of a car tire, and let some air escape. It is not cool inside the tire, but as the air comes out it expands and thus cools." explained by Paul Shepson, professor of atmospheric chemistry at Purdue University's School of Science

    • @sunshinespecial
      @sunshinespecial 5 лет назад +2

      @@nayandeori2143 Yes that is correct. But due to expansion, the pressure decreases. Actually, with increase in altitude/height the temperature decreases, so, the atmospheric pressure also decreases, and the air expands due to lower pressure over it.
