what are the forces that produce weather?

Answer 1

Our weather is produced by the heat of the sun, but to form clouds you need a material that can evaporate (turn into a gas) and rain (turn into a liquid) when it gets colder.

Sun, liquids like water, dust and terrain create and shape our weather.

Clouds form around dust particles that collect liquids, on Earth it is water, although sulfuric acid, creating acid rain, has been occasionally created by pollution. Most of that was caused by the US, but they have gotten better at pollution control.

Ultimately the thing that drives all weather is the sun. As the earth rotates some areas cool and other areas warm up; as the Earth spins on its axis it also moves some air, but only in one direction. When the warm air at the equator sucks up the water evaporated from the seas it rises and expands. The colder air from the North and South Pole loses water and falls, it flows toward the equator to replace the rising warmer air and then it too gets warmed and holds more evaporated water.

The collision of air masses is what causes the weather. As cold air hits warm air, it cools down and can’t hold all the water in it. This water falls as rain, if it gets cold enough then it becomes snow, sleet or hail. If the air masses form a rotational pattern then they can create tornados, hurricanes or the South Seas version called cyclones.

Vapor has to collect around dust particles to form clouds, a lot of the rain clouds in the US get their dust from The Sahara Desert.

Katrina was born in the deserts of the Sahara and the warm air mass traveled across the Atlantic Ocean picking up evaporated water along the way. As it did it met southward flowing colder air masses and formed a tropical depression. The tropical depression developed rotational movement and a hurricane was born. It ran around in the warm water of the Gulf of Mexico and gathered more water and so more strength. Once it hit land it lost its source of water and so it lost strength.

This year something unprecedented happened, a hurricane threatened Greenland. Normally hurricanes never make it that fare north, they die somewhere in the Atlantic when they run out of power. The effects of Global Warming has started melting the Artic Ice Cap and allow a hurricane to travel further north than it is normally possible.

When clouds full of rain hit mountains they can’t cross those mountains. In Brazil the water is forced out into Rain creating the Amazon and the Rain Forest. In California the deserts of Arizona, New Mexico and on up to Washington state are caused by the intervention of the Rockies. The rain clouds can’t pass the mountains so they water the western side.

If the sun didn’t exist then the atmosphere would freeze solid and fall like on Pluto. Even then when one side turns toward the sun the helium warms up and melts into a liquid at a few degrees above 0 degrees K.

On Saturn, Uranus, and Jupiter there are raging winds with huge bands of clouds rotating around the planet; all caused by the warmth of the sun.

It is the effect of the cooler and warmer spots that creates air movement, the existence of a liquid which can evaporate adds to that air movement creating weather. On earth it rains water, on Saturn and Titan water is a solid and it rains methane, while on Venus it is sulfuric acid. In each case it is the sun that starts the weather.

The factors that create weather are: a liquid that can vaporize and fall out as rain, the terrain that can hold that liquid and force it to fall out, and dust which can form the nucleus for the liquid to collect around creating clouds. Liquids like water on earth and methane on Saturn’s moon Titan help drive the weather there. Terrain holds this liquid and stops it form passing; mountains form deserts on the other side, the Sahara is caused by the Himalaya Mountains. The rain forests of Brazil are caused by the water being unable to cross the Andes Mountains. Dust particles are the source of clouds allowing the evaporated liquid to gather around them. The winds are driven by the sun and by increasing and decreasing temperatures; this is why it is always coldest before the dawn. The rising sun warms the air causing it to rise and thus creating a wind when the cooler air from the night side rushes in to replace it.

Answer 2

This is a very good question. What you need to understand is that the atmosphere attempts to establish a balance as the wind moves. What are the major forces at work here? Well first is solar radiation, then there is a rotating earth in an orbit about the sun and inclined to its orbit. This generates unequal heating on the earth's surface and in its atmosphere. Unequal heating causes pressure differences which initiate the movement of the atmosphere which we call the wind. The Coriolis acceleration begins to act on the moving wind causing it to move to the right in the northern hemisphere and to the left in the southern hemisphere. There is also a force caused by surface friction which tends to slow the wind down. When there is a perfect balance the wind is said to be in geostrophic balance. In this case the wind flows parallel to the isobars (lines of equal pressure). But since this never occurs perfectly the winds tend to cross the isobars rather than run parallel to them. Around a low pressure center the pressure gradient acts inward toward the center of the low. The Coriolis acceleration acts to the right of the flow or in the opposite direction of the pressure gradient. The friction acts along the direction of motion. The result is wind that tends to spiral into the low. An opposite situation is established with an anticyclone. Hope this helps a little. I could do it much better on a blackboard.

Answer 3

The most important force that creates most of the weather conditions is the pressure gradient force between many high and low pressure systems.The pressure gradient ,in turn,depends upon the temperature gradient which in turn is caused by the unequall heating of the earth's surface by the incoming solar radiation.
The temperature gradient between the equator and the poles are responsible for the low pressure belts at the doldrums,low pressure belts at 60 degree latitude N and S,and high pressure belts called horse latitudes and polar high in both hemisphere.This causes the global winds like trade winds,westerlies and polar easterlies which also contribute to the global weather conditions.
The permanent vertical pressure gradient force(or temperature gradient force) causes convective currents resulting in the formation of many clouds and storms in the troposphere.
The density gradient force in oceans induce ocean currents which softens the extreme weather conditions along the shores of many continents.

Answer 4

Sweet Jesus those are some long and complicated answers. Let me try to give it to you simply.

All weather that happens on Earth is simply the Earth trying to balance out. More sun hits the equator, so it's hotter than the poles. Weather is simply the Earth moving energy around to try and equalize everything.

Answer 5

the troposphere are the forces that produce weather

Answer 6

Solar energy is the only force.

Wind, precipitation, ocean currents and storms are all driven by solar energy.
