Why air warms when it sinks

Now, the important thing is that warm air can hold more water than cold air. Therefore, when warm air rises, the air may not be able anymore to hold all the water that it has. If there is a lot of water, the drops can get bigger and bigger until they are heavy enough that they fall from the sky — it rains. So, the movement of cold and hot air brings all kinds of weather to the planet. It makes wind, and rain, and snow. Similarly, it becomes a challenge to retain heated air indoors during winter.

Doors and windows are the most apparent culprits behind air leaks in your home. However, gaps, drafts, holes, broken weatherproofing sealings are some of the less obvious and hence neglected reasons leading to heat loss. It is important to get your home inspected for any air leaks before the start of peak seasons. The next step should be caulking all the leaks and weatherstripping your windows and doors. Since hot air rises and cold air sinks, fans come in pretty handy to get the settled air moving around your home.

In summers, run your fans in the counterclockwise direction. Even though fans do not cool a room , they do a better job of increasing airflow when coupled with an air conditioner. Since cooled air settles closer to the floor, running a fan would create a cool breezy effect all around your room.

This even helps you set your thermostat a couple degrees higher, hence saving energy. While fans are popular in summers, you may be surprised to know that they can be pretty useful in winters too. You just have to change their direction to clockwise for the colder months. Running your fan then helps to disperse it throughout your room.

Indoor fireplaces make a vintage statement while adding warmth to your interior. The aroma of burning wood and the sound of firewood crackling are unmatchable pleasures. But all this comes at a cost. Since hot air rises, it escapes through the chimneys. Fireplace flues the passageway inside your chimney are a major source of air leaks.

The flues are usually made of metal, and extreme temperature changes can cause cracks, leading to heat loss. Sinking air is the primary reason why high pressure leads to sunny days.

Strong high pressure over the continental United States also forces the jet stream, a source of cooler air, to the north and allows warm, moist air from the Gulf of Mexico to move inland at the surface.

As is often the case for this time of year, high pressure has been more or less entrenched over Texas this August. Will it remain so, more or less, for the rest of the month? Explanation: As an air parcel sinks the pressure of the surround air around it increases.
