how the low pressure depletion takes place? how it is related with rain?

Low pressure is related with storms\nHigh pressure is related with good weather\n\nThe way i understood is... that is a measure of air pressure\nif its sunny then all the air above is pushing down\n\nif there are storms there is water and stuff in the air taking up space therefore less air pushing down \n\ndoes that make sense

In meteorology, a tropical storm is a storm system with a closed circulation around a center of low pressure, fueled by the heat released when moist air rises and condenses. The name underscores their origin in the tropics and their cyclonic nature. They are distinguished from other cyclonic storms such as nor'easters and polar lows by the heat mechanism that fuels them, which makes them "warm core" storm systems.

When the atmosphere of an area heats up it expands, when it expands it occupies a larger volume than before, but the weight (mass) of this atmosphere is the same as when it was smaller, so it now it exerts less force per square area than when it was colder..so the pressure is lower, See formation of a hurricane. Hot air, causes low pressure, rises  and allows air from hi pressure area to rush in to equalize pressures

A large storm pulls energy from as far around as it can reach. Therefore if the storm moving is pulling all the heat and moisture out of the air around it, then there is a void of mayhem, a calm, before the actual storm throws back all that was there to begin with.

The individual drops of rain usually form as pure drops of water.  As these drops fall, they encounter gases in the atmosphere which can be absorbed and react with the water.\n\nMost of the gases are oxides of nonmetal elements.  When they react with water, they form acids.  This is the source of "acid rain."\n\nFor example Nitrogen dioxide reacts with water to form nitric acid.

It indicates a drop in pressure which usually means windy weather on the way and probably rain too.

The pressure is high at the surface where air is slowly descending — much too slowly to feel. And, this is going on over a large area, maybe a few hundred square miles. As air descends, it warms, which inhibits the formation of clouds. This is why high pressure is generally — but not quite always — associated with good weather

Storms are created when a center of low pressure develops, with a system of high pressure surrounding it. This combination of opposing forces can create winds and result in the formation of storm clouds, such as the cumulonimbus. Small, localized areas of low pressure can form from hot air rising off hot ground, resulting in smaller disturbances such as dust devils and whirlwinds.

The shape of a drop of rain is constrained by the surface tension, which tries to give it the shape for which the surface area is minimum. For a given volume, the spherical shape has the minimum surface area. That is why rain drops acquire spherical shape.

Are any of you educated in science?\n\nBernoulli's Principle states that as the speed of a moving fluid increases, the pressure within the fluid decreases. It has absolutely nothing whatsoever to do with air pressure and temperature. You're thinking of either Charles's Law or Boyle's Law, but again neither have any relevence here.\n\n\nHow possibly can hurricanes affect the water pressure in Latin American countries? Don't they get hurricanes in the US and does the US have a water pressure problem?\n\nWater pressure, the hotter the air (also water) the lower the pressure, thats why hurricanes form in the carribean region ( they need moist{sea} warm air)\n\n\n\nThe next answer is actually theoretically correct, you do weigh less at the equator than at the poles, but the effect is small (0.5% weight difference) and certainly doesn't have a significant effect on the plumbing in Latin America. This is equivalent in a 10 storey hotel to raising the roof storage tank by approximately 6inches or 15cms to negate this effect:\n\nWell pardner, my guess would be that centrifigal force at the equator is greater than at areas further north and further south. The ideal launch sites for stuff being flung out into space would be close to the equator for the same reason.\n\n\nThe real reason as any competent plumber will tell you is a combination of the head of water (the pressure the water is being fed with) and the diameter of the pipes, smaller pipes allowing less flow. The pressure of the water is dictated either by the water supply companies who pump the water at a certain pressure (Mains pressure) or if the system is being fed from a tank, it depends how high above the tap the water tank is. Higher tanks give higher pressure, which is why a shower on the ground floor fed from a tank in the loft gives a better flow than one on the top floor.\n\nBasically, they've got rubbish plumbing and it's being fed either at a lower pressure by the utility companies or they are using smaller diameter water pipes, all probably compounded by general drinking water shortages.

A storm is any disturbed state of a planet's atmosphere, especially affecting its surface, and strongly implying severe weather. It may be marked by strong wind (a wind storm), thunder and lightning (a thunderstorm), heavy precipitation, such as ice (ice storm), or wind transporting some substance through the atmosphere (as in a dust storm, snowstorm, hailstorm, etc).\n\nFormation\nStorms are created when a center of low pressure develops, with a system of high pressure surrounding it. This combination of opposing forces can create winds and result in the formation of storm clouds, such as the cumulonimbus. Small, localized areas of low pressure can form from hot air rising off hot ground, resulting in smaller disturbances such as dust devils and whirlwinds.\n\nYou could get more information from the link below...

It depends on a number of variables. One factor is the temperature difference between two air masses. The warm air will hold more water than cold air, so if a warm front hits a very cold air mass the cold air will cool the warm air and it will become oversaturated with water vapor. The more the warm air is cooled the more rain will fall. \n\nAnother factor is the way the air masses are moving. If a warm front moves over cold air slowly it will form a gradual transition with the cold air remaining near the ground and the warm air climbing gradually over it. This will produce a prolonged period of rain. If a cold front pushes under a warm air mass it may form a much steeper boundary area between the two air masses. This can produce very hard short periods of rain. \n\nHere's a little diagram:\nhttp://www.tiscali.co.uk/reference/encyclopaedia/hutchinson/m0006324.html

It rains\nthe rain collects and then either:\n\nsoaks into the ground and comes out later\nflows into a river then the sea\n\nAt some point it evaporates and forms clouds\n\nthen it rains...\n\nsee above!

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.

Well, first off it's probably in the tropics...  ;)\n\nI cut and pasted this part (sorry, feeling lazy):\n\n"In meteorology, a tropical cyclone is a storm system with a closed circulation around a center of low pressure, fueled by the heat released when moist air rises and condenses. The name underscores their origin in the tropics and their cyclonic nature. They are distinguished from other cyclonic storms such as nor'easters and polar lows by the heat mechanism that fuels them, which makes them "warm core" storm systems.\n\nDepending on their strength and location, a tropical cyclone can be called a tropical depression, tropical storm, hurricane, or typhoon, among other names.\n\nTropical cyclones can produce extremely high winds, tornadoes, torrential rain (leading to mudslides and flash floods), and drive storm surge onto coastal areas. Though the effects on populations and ships can be catastrophic, tropical cyclones have been known to relieve drought conditions. They carry heat away from the tropics, an important mechanism of the global atmospheric circulation that maintains equilibrium in the environment." (wikipedia - see below)

err..well if you mean as in..acid rain..\nin most areas in the US, rain is slightly acidic.\nIf the rain is unpolluted, then the acidity comes from a weak acid called Carbonic Acid which forms when carbon dioxide reacts with the water. Any extra acidity in rain is a result of pollutants. The two main chemical components are nitrogen oxides and sulfur oxides which react with water to form nitric acids and sulfuric acids. These pollutants come from cars, buses, all that kind of stuff. (:
