What causes weather?

Answer 1

To put it as simple as I can, weather is nothing more than nature attempting to equalize the global heat balance on earth.

The the unequal receipt of energy from the sun (for all practical purposes the source of all our energy) causes great imbalance which mother nature abhors.

After that, the explanation becomes very long and complex.

Answer 2

What Causes Our Weather

Answer 3

Who-WEE! Lots of things! The most prominent thing is the Coriolis force, created by the Earth's rotation. You need to study this to explain it; it's weird.

Another thing: the presence of water and heat (usually solar but very often from other sources such as volcanoes and lately, human industry).

Anytime water is heated, it becomes unstable, expands and rises. This could result in something as localized as a thunderstorm or something (posed by scientists) as catastrophic as a global, New Ice Age!

After the water is heated, then it connects with various wind currents created by the Coriolis force and anything is possible!

Another major factor that has received much (deserved) attention lately is the movement of ocean currents from the Equator to the pole, especially to Northern latitudes.

This movement of warmer water (good example: the Gulf Stream--called "The Conveyor Belt"), from areas like the Caribbean, up to northern latitudes), moderates temperature and precipitation, (to name a few things) in both tropical AND northern climates, resulting in the fact that, for instance, England and countries like Norway are habitable).

If this "Conveyor belt" (of fresh water, which then sinks and returns to the Equator) were to stop, then temperatures would drop drastically and places like London, New York, and even Moscow would become uninhabitable.

This is NOT science fiction! The only thing scientists are not sure of is exactly WHEN this will happen. Could be 100 yrs....could be 10!

Another HUGE impact on our weather is global warming, due to the retention of "greenhouse gases", mostly produced by industry, causing the polar and other ice sheets and glaciers to melt.

One might say, well, then things will warm UP, right? Yes, but only briefly. As more CO2 and other gases spew into the air, more sunlight is reflected back into space, causing the temperature to DROP. We have ample evidence of this happening in the past, as in 1812, "The Little Ice Age" or after 1883, the "Year Without a Summer", after the eruption of the volcano, Krakatoa in the South Pacific.

The result (aside from earthquake and tsunami deaths) was widespread famine and disease, in both cases.

Whatever you think about Al Gore and other environmental activists, this stuff is REALLY happing! Just watch the film "The Day After Tomorrow", slow it down a bit, timewise, and ignore the extremes (a bit) and you'll have a VERY good idea what will happen if we don't arrest greenhouse gases NOW...and even that may be too late!

Here are some links for you...I'm glad you asked this! Weather nowadays, is a LOT more than just knowing when tornadoes or hurricanes might hit...sadly!

Answer 4

The fundemental thing that is responsible for the various weather condtions is the solar radiation.Due to the the differential heating of the sun, within the land masses and between land mass and sea area, different pressure systems are created which causes the weaher.

Answer 5

A whole bunch of stuff!!
The rotation of the planet moves the atmosphere. The sun causes heating of the air and oceans, which causes air currents. As air currents move they push molecules together causing changes in heating and air pressure. Mountains block air flow so wind patterns change. Thats about 1% of the things that cause weather.

Answer 6

The earth atmosphere mostly the troposphere causes most of the weather in the world.

Answer 7

Reducing it to the most simplistic answer, I would say it has to be solar radiation and moisture in the lower atmosphere. Without it, none of the other actions (such as the coriolis effect) would create weather.

Answer 8

global warming!!
