Barriers that prevent moisture-laden air from flowing include mountains, large bodies of water, and temperature inversions. These features can cause the air to rise, cool, and release its moisture in the form of precipitation.
Humidity
Mountains are a common barrier that blocks the flow of moisture-laden air, causing the air to rise, cool, and release precipitation on the windward side. This process is known as orographic lifting. Additionally, high-pressure systems can inhibit the movement of moist air masses, leading to dry conditions.
Tall mountains can block the flow of moisture from the windward side to cross over to the leeward side, causing a desert to form. As the moisture laden air hits the mountains it is forced up into the atmosphere where it forms rainclouds that then drop their moisture on the windward side. The air that does flow over the mountain is now devoid of any moisture and the region on the leeward side of the mountain becomes a desert.
Moisture-laden air is air that contains a high level of water vapor. It usually feels humid and can lead to condensation, fog, or precipitation when it cools down. This type of air can affect weather patterns and influence how we feel in terms of comfort and health.
Frequently mountain ranges will block the flow of moisture laden air off an ocean from crossing into the interior of a continent. The moisture is forced upward by the mountains where it condenses and falls as rain or snow on the windward side of the mountains leaving a rain shadow desert on the leeward side. See the image above.
Yes, and often does, when Arctic cold fronts collide with warm, moisture laden air.
You do not ever want to block or restrict air flow to a return air grille.
Yes you can
Exhaled air is saturated with water vapor because the air we breathe in gets warmed and humidified in our lungs. As we exhale, this moisture-laden air is released, resulting in saturated air.
Desert areas often form on the inland slopes of coastal mountains because the mountains block the moisture-laden air from reaching the leeward side, creating a rain shadow effect. This lack of moisture leads to dry conditions and lower precipitation, which are characteristic of deserts.
