wind is caused by the movement of air from regions of high atmospheric pressure to regions of low atmospheric pressure.  high pressure is caused by the cooling of air: as air cools, it shrinks and becomes more dense and its pressure therefore increases.  low  pressure is caused by the heating of air: as air warms, it expands and becomes less dense and its pressure therefore decreases.\nrain is caused by the rising of columns of air: when a bubble of air is warmer than its surroundings, it expands and becomes less dense.  this less dense air rises, and as it rises, it gets cooler.  as it cools, it becomes less able to hold moisture.  eventually, you reach a point at which the air can no longer get any cooler without having to lose some moisture.  it is at this point that clouds and rain start to form.\nyou get storms if you have the right combination or rain, wind, air pressure, humidity, and clouds.

the reason for cyclone is low pressure region.as we know that wind flows from low to high pressure region and due to the coriolis forces which is the main cause of shifting the air to left or right in northern & southern hemisphere resply.\nwhen low pressure region is created, then normally wind flows to that area.

Generally, storms are low-pressure areas and nice clear weather systems are high-pressure areas.  So if pressure is falling, precipitation might be coming, and if it's rising, better weather might be coming.

Usually, heavy rain stroms are always accompanied by thunderstorms.  The worst storms occur when warm, moist air meets with cool, dry air.  The greater the difference, the greater the thunderstorm and rainfall.

The moon's gravitational pull causes the waves to form.\n\nAnd those waves are what cause wind to be generated.

"Wind is the roughly horizontal movement of air (as opposed to an air current) caused by uneven heating of the Earth's surface. It occurs at all scales, from local breezes generated by heating of land surfaces and lasting tens of minutes to global winds resulting from solar heating of the Earth. The two major influences on the atmospheric circulation are the differential heating between the equator and the poles, and the rotation of the planet (Coriolis effect)."

The main hazards of a tornado include extremely high winds, flying debris, and sometimes the associated weather phenomena, such as large hail and heavy rain. The extremely high winds pick up debris, causing seemingly harmless things such as small pieces of styrofoam or wood to become lethal projectiles. The winds can also cause extensive structural damage. The storms associated with tornadoes also bring hazards such as baseball-sized hail and intense rain around the vicinity of the tornado.

Nobody is really sure, because we weren't there when they formed.  But, the most popular theory says that early in Jupiter's history there were a lot of storms in Jupiter's atmosphere (much like the great red spot).  If you've ever watched the weather then you know that big storms, like hurricanes, rotate either clockwise or counterclockwise depending on if they are north or south of the equator.  Take for instance a storm rotating clockwise:  on the northern edge of the storm the clouds would be moving to the right (or east) while on the south the clouds would be moving left (or to the west).  The same would be true of storms on Jupiter.  Now, because Jupiter rotates so quickly (a day on Jupiter only differs from our day by a few hours, but it is hundreds of times larger and must be rotating a lot faster), these storms aren't strong enough to hold themselves together and start getting stretched out along the top of the atmosphere around the surface.  As this happens the direction the clouds are moving in the storm remains the same, so after a few days of rotating, the storm is completely stretched out and wraps completely around the planet leaving a band of clouds moving to the right around the planet and a band of clouds moving to the left around the planet.  Do this twenty or so more times and suddenly the entire planet is covered with alternating bands of clouds moving left, right, left, right....and so on.

Hurricanes are intense low pressure  areas that form over warm ocean waters in the summer and early fall. Their source of energy is water vapor  which is evaporated from the ocean surface. Water vapor is the "fuel" for the hurricanes because it releases the "latent heat of condensation" when it condenses to form clouds and rain, warming the surrounding air. (This heat energy was absorbed by the water vapor when it was evaporated from the warm ocean surface, cooling the ocean in the process.) Usually, the heat released in this way in tropical thunderstorms is carried away by wind shear, which blows the top off the thunderstorms. But when there is little wind shear, this heat can build up, causing low pressure to form. The low pressure causes wind to begin to spiral inward toward the center of the low. These winds help to evaporate even more water vapor from the ocean, spiraling inward toward the center, feeding more showers and thunderstorms, and warming the upper atmosphere still more. The showers and thunderstorms where all of this energy is released are usually organized into bands (sometimes called "rainbands" or "feeder bands"), as well as into an "eyewall" encircling the center of the storm. The eyewall is where the strongest winds occur, which encircle the warmest air, in the eye of the hurricane. This warmth in the eye is produced by sinking air, which sinks in response to rising air in the thunderstorms. The winds diminish rapidly moving from the eyewall to the inside of the relatively cloud-free eye, where calm winds can exist.\nhurricane eyes seen from the Space Shuttle and from aircraft\nHurricane intensity is based upon the highest sustained (1 minute average) wind speed the hurricane is producing. The "Saffir-Simpson" scale rates hurricane strength in this way from Category 1 to Category 5. These categories were chosen based upon the amount of damage that each category can produce.\nIntensity Wind Speed Damage\nCategory 1 74- 95 mph MINIMAL: tree branches, shrubs, unanchored mobile homes\nCategory 2 96-110 mph MODERATE: mobile homes, poorly constructed buildings, some trees down\nCategory 3 111-130 mph EXTENSIVE: small buildings damaged, large trees down, mobile homes destroyed\nCategory 4 131-155 mph EXTREME: outer walls damaged, roof failure on small buildings, extensive damage to doors and windows, mobile homes destroyed\nCategory 5 >155 mph CATASTROPHIC: complete roof failure on many buildings, some buildings destroyed, severe window and door damage, mobile homes destroyed\nIn low-lying areas, much of the damage from hurricanes can be from the "storm surge", in which water being blown onshore by the high winds rises rapidly. The storm surge can destroy the lower floors of some buildings, or even destroy the foundations of residences causing the homes to wash away. The storm surge can also trap residents from evacuating along low-lying escape routes.\n\nHurricanes almost always travel poleward at the end of their life cycle, helping to transport excess heat out of the tropics toward higher latitudes. They gradually die as they move over cooler waters, which do not have the heat energy necessary to evaporate sufficent water vapor into the atmosphere to fuel the hurricane. If the hurricane crosses over to land, the heat source is removed entirely. With the removal of the energy source, and the greater surface friction of the land's terrain and vegetation, the hurricane's winds rapidly decrease.

Prevailing winds off the coast of Africa blow hot air over the relatively cooler ocean. Given that hot air rises, this creates a zone of low pressure that rotates given the Coriolis effect. As the hot air blow over the ocean, it causes a higher rate of evaporation. As more and more moisture is pulled from the ocean, it produces more powerful rainclouds that quickly turn into thunderstorms rotating around this center of low pressure. This is the engine of a hurricane: hot air is sucked in underneath the clouds over the ocean, and pulled by the lower pressure into the eye, which draws the moisture up to the top of the hurricane and condenses.

Wind is the roughly horizontal movement of air (as opposed to an air current) caused by uneven heating of the Earth's surface. It occurs at all scales, from local breezes generated by heating of land surfaces and lasting tens of minutes to global winds resulting from solar heating of the Earth. The two major influences on the atmospheric circulation are the differential heating between the equator and the poles, and the rotation of the planet (Coriolis effect).\n\nGiven a difference in barometric pressure between two air masses, a wind will arise between the two which tends to flow from the area of high pressure to the area of low pressure until the two air masses are at the same pressure, although these flows will be modified by the Coriolis effect in the extratropics.\n\nWinds can be classified either by their scale, the kinds of forces which cause them (according to the atmospheric equations of motion), or the geographic regions in which they exist. There are global winds, such as the wind belts which exist between the atmospheric circulation cells. There are upper-level winds, such as the jet streams. There are synoptic-scale winds that result from pressure differences in surface air masses in the middle latitudes, and there are winds that come about as a consequence of geographic features such as the sea breeze. Mesoscale winds are those which act on a local scale, such as gust fronts. At the smallest scale are the microscale winds which blow on a scale of only tens to hundreds of metres and are essentially unpredictable, such as dust devils and microbursts.\n\nYou could get more information from the link below...

Actually, it is the rotation of the earth that causes weather and then clouds.\nThe clouds move across the sky as a result of differences in heat between regions. All of the matter around the earth is held to it by gravity. However, clouds "float" in air. So they will move at slightly different speeds. \n\nEver watch when they stir a milkshake? the different colors all swirl similarly.

Exactly the same thing as on Earth:  Differential heating caused by the Sun's rays falling on different latitudes of the planet.  This causes the warmer parts of the atmosphere to rise.  Denser atmosphere "blows" in to fill the lower pressure areas (think wind).  If the atmosphere contains materials that can condense(water, vapor, methane, ammonia, etc.) and the temperatures are in the correct range for the atmospheric contents then "weather" occurs.

No, mother nature is mother nature. Storms have always been a part of the climate. Earthquakes because the Teutonic plates shift. Tornado's by severe storms. Why would you assume that God would be out to get us? He created everything( if that is your belief) so it follows that He created the weather too.
