I guess that the air pressure is high to begin with. because it needs to
evaporate the water from the soil. Nevertheless as the water is evaporated in
the atmosphere it becomes considerably dry. Meaning that the atmosphere
is full of water vapour and so the pressure changes to low in order to
precipitate and then it rains.
What else can I help you with?
Is it humid when it rains?
Yes, it is typically humid when it rains because rain is often associated with moisture in the air.
What is the humidity level when it rains?
The humidity level when it rains is typically high, as rain is a result of moisture in the air condensing and falling to the ground.
The air pressure on a rainy day is usually air pressure on a sunny day?
That's incorrect! The air pressure on a rainy day will relatively be lower than that on a sunny day. On a sunny day the air pressure is at or around about 14.1 lbs/in^2 where as on a rainy day it will be somewhat lower at around about 13.78 lbs/in^2 or lower. The weather is determined by the elevation being above or below sea level. Hence when it rains the elevation is below sea level which results in the drop of atmospheric pressure.
Air moves from a point at which air pressure is to a point at which air pressure is?
higher. This movement of air is driven by the pressure difference between the two points. The air flows from areas of higher pressure to areas of lower pressure in an attempt to equalize the pressure.
How are monsoons made?
Air on the sea cools, while air on land warms up. This causes a area of high pressure over the sea and an area of low pressure over the land. Of course air flows from high pressure to low. This causes the air to bring water vapor on to land. convection causes this humid water to rise. Once this air rises and there is a lot of condensation in the air brings large rains. :) :)
What is temperature of the air and cloud when it rains?
The air temperature of the air is cold when it rains and the cloud temperature is cold when it rains
What happens when air pressure is cooled?
When air pressure is cooled, the air molecules move more slowly, causing them to come closer together. This increase in density leads to a decrease in air pressure. Additionally, cooling air can lead to the condensation of water vapor, which can lead to the formation of clouds and precipitation.
How a rain alarm works?
It's based on the air pressure measurement of the environment. Before it starts to rain pressure dramatically drops. That's particularly why some people have headaches before rains.
Cover your air conditioner when it rains?
NO
When it rains what kind of pressure is in the atmosphere?
Rain most often occurs with low pressure.
Why do leaves turn over before it rains?
Leaves turn over before it rains because they are sensitive to changes in humidity and air pressure. This response is triggered by the anticipation of rain, as the underside of the leaf is better equipped to absorb water and nutrients when it does rain.
Why does a barometer fall before it rains?
Air pressure is the weight of the air around us. When there is a period of low pressure, a barometer detects this and displays it with the needle. This reading is showing the weight of the air. It normally rains during a period of low pressure, so if the needle on the barometer is pointing to low pressure or rain, you can predict what the weather will be like in the following days. Hope this answers your question.
Why do leaves flip over before it rains?
Leaves flip over before it rains to protect themselves from getting wet and to reduce water loss through their stomata. This behavior is believed to be a response to changes in humidity and air pressure that occur before a rainstorm.
Is it humid when it rains?
Yes, it is typically humid when it rains because rain is often associated with moisture in the air.
What do worms do for air when it rains?
Get to higher ground or drown.
What is the result of a cold air mass pushing against a warm air mass?
it rains
Why does your radio and lights come on when it rains without the key being in the ignition?
This is extremely strange and may not have anything to do with the rain. There could be a short in the wiring system that is triggered by the atmospheric pressure in the air.
