How does a cold front work?
139451
A front is a boundary between warm and cold air. With a cold front, you have an area of cold air moving into an area of warm air. You can pick them out on weather maps as a blue line with blue triangles. The triangles point in the direction the front is moving. \n\nSince cold air is heavier than warm air, the cold air pushes underneath the warm air, causing the warm air to rise. The warm air then condenses as it reaches cooler altitudes, creating clouds and, eventually, precipitation. \n\nIf the difference in temperatures is very large, you can get a strong front that can create thunderstorms, or even tornadoes. Luckily around here, the Pacific Ocean keeps the temperatures differences to a minimum.

A front is a bank of cloud that seperates warm air and cold air. A cyclone is the name given to hurricanes in the Indian and Oceanian Oceans.

THEORETICALLY, you'll get better gas mileage on cold days because you're ramming more air into the engine.  And the TIRES (the biggest waste of energy is heating up the tires instead of pushing the car forward) are going to run cooler, too.  \n\nThe heater steals less energy from the engine than an airconditioner, too, another plus for cold days.\n\nIf you have that sensor that adds gas on cold days, it depends on how much gas it adds during cold weather.

The jet stream is a current very high speed air 6-12 miles above the earth. It flows from west to east carrying with it weather systems. For example, it pushes cold dry air, warm moist air, low pressure, high pressure, etc. The jet stream is the main reason we have cold fronts. It pushes large masses of cold dry air usually to the south or east. You rarely see cold fronts going north or west because the jet stream flows the other way. The jet stream also pushes pressure systems around, causing sunny weather or rainy weather. To answer your second question, the jet stream doesn't really affect cyclones or anticyclones because the jet stream is so high up, and high pressure usually controls a cyclone's movement. \nBasically, if we didn't have a jetstream, all the weather patterns that currently are in place would stay where they are. If it's sunny and dry, it will stay that way. If it's rainy, it'll still be rainy.

Cold fronts, fast-moving jet stream, dry line, occluded front, and cold dry air moving into warm moist air will all contribute to extreme weather.  Often, in the southwest by the panhandles of Texas and Oklahoma as well as New Mexico, several of these factors will occur at the same time which can result in a severe weather outburst with several tornadoes, large hail, and lots of rain.

You may be right.  The force that they respond to is gravity.  Cold air, being denser, will, in a fluid medium, be drawn closer to the earth, displacing warmer, less dense air.

They get cold. \n\nThere are some effects on magnetic properties when you go very cold (search on magnetism AND temperature) especailly for electromagnets. Some things which aren't magnetic start to become so and things which are magnetic become more so. You wouldn`t notice much if you used a home freezer, you need to get much closer to absolute zero.    \n\nMaking it hot has a more important effect. A permanent magnet heated to above its Curie temperature will lose its properties.

Cold temperatures- like that of ice- slow down molecules and keep them closer together.  Higher temperatures- like that of gases- speed up molecules and let them get lose and fly wherever they want.

Cold fronts can form thunder storms and tornadoes, with worse storms coming when there is more difference in temperatures on the 2 sides of the front.

Because all cold air is created in the freezer. The fridge gets cold by leeching off the freezer.  There is only one compressor. Cold air sinks, so it falls into the fridge.\n\nUnits like side by side and bottom freezers need a fan to get the cold to the fridge. A top freezer doesn't.

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

Heat transfer can occur through convection (ex: In the winter, the wind makes you colder), conduction (ex: heating a pot of water on an electric stove), and radiation (ex: sunlight warming the earth).

Sorry you have had so much grief with the cold weather.\n\nWell, winter usually does bring cold weather and not knowing where you are, would give us a clue as to why, but I bet forecasters did give a hint that it might be that way.

As my college chemistry professor said:\n\nOn a warm day, ther-mo-dy-nam-ics tells you that your cold beer is not going to get colder, it's going to get warmer so you better drink it sooner rather than later.\n\nThus, heat flows from hot to cold, not cold to hot.\n\nAnother way to look at it this.  Cold is not the presense of something, it is the absense of something.  It is the absense of thermal energy.  At absolute 0, there is now thermal energy in the system.  While placing something hot in the system will make the hot thing colder, it is because the thermal energy is migrating from the hot thing to warm up the cold surroundings.

Based on the fact that cold causes things to contract (I won't go into a chemistry spiel) that the golf ball would therefore have less room to retract thus it would not travel as far. Similar to the way a cold basket ball does not bounce as high as a warm one. The Cold air contracts. Hope this helps!

Another thing to remember about fronts are that.... not all "cold fronts" have cooler air behind it.  Sometimes, its nothing more than drier air.\nSame goes for warm fronts.  Could just be a surge of moisture.... displayed as a warm front.\nAnother common misconception about fronts is "thunderstorms, and severe weather only happen at COLD FRONTS."\nNOT TRUE.  Warm fronts are a common trigger of storms, as they are a source of lift..... though not as much as you would see with a cold front.\nThen again, that's not to say.... that severe weather will always occur at at either.  Thermodynamics, and upper-air conditions play the big role in it all.  In fact, not ALL fronts (be them cold or warm) are associated with precipitation.\n\n\nHope this helps.\nTake care...\nWeather_Wise911

Cold falls so the cold created in the freezer helps to keep the fridge part cool also.\n\nCoach
