what is wind patterns ?

Wind Patterns probably refer to the Global Wind Patterns or Prevaling Winds that are associated with different latitudes.\n\nThis is probably best illustrated by the figure from the Texas A&M Desesrts course web site referenced below.\n\nTo summarize, \nthe polar latitudes between 60 and 90 degrees (both north and south) have prevaling "Polar Easterly" winds.\nLatitudes between 30 and 60 degrees (again both north and south) have prevaling "Westerly" winds.\nThe region between 30 degrees north to 30 degrees south have prevaling easterly "Trade Winds."

The most common wind-formed deposit is the sand dune, found in deserts and on the shores of oceans and lakes. Dunes are formed by sand accumulating around any object that serves as an obstacle to the wind. As windblown sand is deposited in the lee of such an obstacle, the wind is slowed still more, and the dune continues to grow. Dunes in some localities may reach a height of 200 m (650 ft). When materials finer than sand are carried by the wind and finally dropped to the ground, the deposit that results is known as loess. Thick layers of loess are found in Europe and the Americas, and loess deposits of Asia reach a thickness of several hundred metres. They are the basis for some of the richest agricultural soils of the world.\n\nMicrosoft ® Encarta ® Encyclopedia 2005 © 1993-2004 Microsoft Corporation. All rights reserved.

A gyre is any manner of swirling vortex. It is often used to describe wind or ocean currents, for example the North Pacific Gyre

tradewinds\n"During El Niño events, the normal pattern relaxes. The tradewinds weaken, particularly west of the Dateline, and the piled-up water in the west sloshes back east, carrying the warm pool with it. The region of rising air moves east with the warm pool, and so does the pumping of heat and moisture into the upper atmosphere. Deflections in the normal wind patterns distort the usual paths of the jetstreams, pushing them from their accustomed places, which eventually causes the changes in the weather that the rest of the world experiences. With weakened tradewinds, the deep cool waters coming up in the east slow their ascent. The food supply for plankton dwindles, and the effect travels up the food chain. When eastern sea surface temperature becomes warm, the east-to-west temperature contrast is small, and so the tradewinds weaken even further, leading to a complete collapse with essentially flat conditions across the entire equatorial Pacific."

There are a lot of great sites that give basic weather predicting information.\n\nDifferences in air pressure are what causes the fronts--high and low pressure. High pressure areas generally have dry, good weather and areas of low pressure have precipitation.

Currents flow in complex patterns affected by wind, the water's salinity and heat content, bottom topography, and the earth's rotation.

Pressure changes affect the wind.  Temperature change determines whether it will rain or snow.

wind is the result of air pressure, air molecules travel from low to high pressure zones, resulting from air warmed by the sun. The strength of the wind i guess would be dictated by the difference in pressure between two zones, and any obstacles it may have to pass over/through in between...

wind is the movement of air\njust like waves are the movement of water

Fronts are defined as the local areas of lowest pressure.  Air flows towards low pressure, so winds are northeasterly north of a warm front and more southerly to the south of it (in the typical northern hemisphere setup).\n\n---\nYou use the term veering (wind changing clockwise with time) like you are looking for a more indepth meteorological answer... but I'm not sure exactly what you are asking when you bring up the air mass and the jet stream.  If you have taken some meteorology classes and are having trouble relating some of the concepts, like Thermal Wind and Quasigeostrophic Theory, let me know by email, and I'll try to help you more.\n\nHope I helped,\nGod bless,\nShane

wind is the result of basically a pressure difference.whenever there is a pressure difference between two places the wind blows from the high pressure side to the low pressure side.this pressure difference can be caused due to several reasond...in summers,the land is overheated and so is the air just around it.the air gets hot and start rising.this tends to lower the pressure of that area.then air from some high pressure area takes the place of that low pressure area.in winters over cooling hightens the pressure of the air.which again tends the air to flow,causing mild winds.near a beach,the heating of the land and the water is uneaven and thus causes the sea breeze during the day and land breeze during the night.

I'm gonna try to answer this...I have no idea how close this is gonna be...\n\nThe jet stream is influenced by high and low pressure gradients which form...In some cases...a strong high pressure will cause a weaker low pressure area to stay stationary right where it's at..This would cause a ridge around that higher gradient with fairer weather and warmer temperatures...\n\nBasically, the jet stream depicts the way storms will track over that given time period, and sometimes gives them higher intensities...\n\nThere are many phenomena that could cause a jet stream to bow like a W...A trough that is cut off from all steering winds could make one area for cool and cloudy while in another section of the country, they could be under high pressure and getting SW flow, meaning they could be having RECORD HEAT!!\n\nUsually when a pattern is zonal, storms are quick to track off as there's not much blocking them...It usually means an absence of weather systems which would mean less chance of convective activity across the area...\n\nI hope this helps..I am a spotter, but I don't have the four to seven years of college other meteorologists do!

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.

On a philosophical level.... I would say it's a natural balance derived from natural occurrences. There are many different forms of weather, but the natural capability of movement shifts in many rotations causing a range of wind that forces climate change and therefore causing dramatic changes and patterns. on more of a documented scientific note I would say:The blanket of air that covers the earth is called\n\n  the atmosphere. The bottom layer of the atmosphere is \n\n  called the troposphere. The troposphere is where all of \n\n  earth’s weather happens. Basically, our weather is \n\n  caused by two things: the sun and moisture in the air.\n\n  These two things together can form clouds, can make rain\n\n  and form thunderstorms, and cause winds to blow. Without\n\n  the sun and moisture in the air, our earth would have no \n\n  weather at all. In fact, there would be no people on our plantet\n\n  \n             Another thing that helps to cause the earths \n\n   Weather is air masses. When two air masses come \n\n   Together, the line between them is called a front. Along a\n\n   Front there is usually clouds, rain, and maybe thunderstorms.\n\n   The movement of air masses helps to cause weather \n\n   almost  as much as the sun and moisture in the air. Without\n\n   air masses, all the earth’s weather would stay in one place
