Explain what happens to all four weather elements when a cold front passes.?
412067
im not sure what u mean by elements. but when a cold front passes warm air is cooled. warm air is able to hold more water than cold thus when it cools it releases it water in droplet form or rain. ussually since cold is heavier the liquid rain with is higher than the cold goes through the cold air and crystalizes and falls as snow. it the cooling effect is too fast ant the droplets fuse and fuse until their weight makes them fall as hail.

If you live in the US, most weather systems track west to east. A low pressure system rotates clock-wise and a high pressure system rotates counter-clockwise. Wind speeds are shown by flags and the more flags, the faster the wind is. Just east of a cold front, which is a low pressure system and takes approx 1 week to travel across the US, is called the "warm zone". It is typically warm and humid. As the cold front passes, the wind shifts to the west. This area is associated with rain, strong winds and thunderstorms. Following the cold front generally mild weather persists as the high pressure system sets in.

High up in the atmosphere where rain clouds form, the temperature is freezing cold. At these aktltitudes the water can freeze. If there is turbulance a drop of water can freeze and be caught in an updraft. A layer of water can form around the frozen rain drop, freezing too. Thti small ice ball falls within the cloud and gets caught up in another up draft. If this continues a piece of hail is produced. It becomes too heavy to stay up and falls to the ground.\n\nIn still air the water is  in vapor form and as the temperature falls below freezing point, molecules of water coalesse and form crystals. If the air is freezing cold all the way to the ground, these crystals fall as snow. If the temperature is slightly above freezing point these crystals melt and form sleet.

All weather is brought about by thermal conditions. Cold as used in the term "cold front" is only a relative term. There is still quite a bit of "heat" in cold air. You must remember all measurements referencing thermal conditions are really a reference to absolute zero where there is no thermal activity.

The warm air pushes the moisture higher into the colder air layers....as the moisture droplets freeze together  they fall and enter the warm air currents which pushes them back up to the cold layers..this happens until enough layers are built up, that the updrafts can't support the weight and the ice falls to the ground in the form of hailstones.

The warm air pushes over the denser cold air and itself cools  - hence the snow. As the cold air gets replaced by the warmer air, we experience  the rain.

Temperature inversions.  Hot air rises and cold air sinks. Normally they pass through each other, but sometimes the atmosphere just flips over pretty fast. Sorry I don't know the circumstances, but I think it has to do with the proximity of of high density air masses.

Thunder / lightning is caused when a cold front and a warm front come together.  More info on lightning can be found here:\nhttp://www.insuremyhouse.com/lightning.html

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

There are many properties but the two most important are:\n\n1. Temperature (cold or warm air mass) - this affects the density of the air mass as well as it's relative humidity, dew point, how it interacts with other air masses of different temperatures, etc. Temperature is the main driver for what types of weather systems will be generated within an air mass.\n\n2. Absolute humidity - the actual water content of the air mass all attributes to the types of weather systems it will generate, and where highs and lows will form.\n\nAlso, air masses can be moving or stagnant, stable or unstable, constant or dynamic, and I'm probably forgetting others.

FIrst the temperature-It is extremely cold in the winter, and cool in the summer.  Then generally the wind-wind can play a major role, especially in mountainous tundra-also in mountainous tundra is the problem of UV radiation.

Abrupt vertical growth on clouds and/or thick cloud layers...   Winds at the surface are typically more southerly just ahead of a cold front and strong temperature and dewpoint discontinuities are found along cold frontal boundaries.  For instance if you're sitting at 49 degrees with a dewpoint of 41, and a city/town west or northwest of you is sitting at 33, with a dewpoint of 17 - most likely you'll have a cold front between you.  Certainly, not always the case, but is generally true.  Your dewpoint depression (the value of your dewpoint subtracted from your temperature) is also typically less than that found behind a cold front.

Ooh, I studied this last semester. It changes phase. In other words, it changes from liquid (water) to gas (clouds) to liquid or solid (rain, snow, or hail). Then it repeats.
