U get an erection when its cold? Dont think u can have 1...unless more blood flows to the penis when its cold? My winky has never been cold!

they call them goose bumps because you get little bumps all over.  It's when your freezing and just can't get warm.  Or you are overcome with a cold chill.  Next time its snowing, stand outside with a t-shirt and see them magically appear.

It rains when the air can no longer hold onto the moisture in an evaporated, cloud form.  It can be cold and rainy, mild and rainy, or hot, muggy and rainy.  \n\nMoisture moves on the air currents. During winter, rain usually comes when it is cold because the air currents bring COLD air from the far north (remember the "jet stream" they talk about on the news?)  But when air currents from the tropics move overhead, temperatures are warmer because it isn't cold in the tropics. And tropical air often brings a huge amount of rain (think hurricanes).\n\nDuring summer, if there is moisture in the air, a lot of moisture, it condenses and turns into liquid form (rain) when temperatures and moisture content of the clouds reaches the right combination.

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.

On cold night's there usually are clouds, it's a correlations that no clouds lets heat disapate faster and therefore it gets colder.

It's not a matter of cold air moving toward warm air, but a matter of the air trying to find equilibrium. Cold air is denser than warm air, and cold air sinks while warm air rises. That's why we feel wind - the colder air rushes in to fill in the less dense air and create an equilibrium.\n\nThis may not be the most meteorologically correct explanation, so any weather people are free to enhance or correct it.

No, wind is caused since warm ail is less dense than cold air. cold goes to warm, causing wind. If all air was the same temperatureair would sit still unless something moved it (fan etc.)

Air temperature may be several degrees warmer than ice surface temperature. Light, including infrared or warmth, is reflected from white surfaces.\n\nThe surface of the ice will melt, slowly, during the day, but it will freeze again over night. That's one of the reasons why a snow field slowly turns into ice.

it means that it's really cold outside

The snow holds pockets of air which act as insulation.Because they are low and round the heat circulates lower in the shelter.The heat is provided by the human body and can be regulated by the individual possessing that body.The igloo also shelters from the elements such as wind chill

the more overcast and humid the air is, the denser it becomes. same happens in case of cold condition. when this happens, the dense air moves the ball more than a light air

Lack of moisture in the air helps static electricity build up.  Cold causes moisture to leave the air.  So, static electricity tends to build up easier in cold climates.

Snow forms when there is cold air (below freezing) and percipitation falls.  Snow is made out of ice crystals.  Sleet occurs when rain falls from warm air (above freezing) and passes through cold air (below freezing) on the way down, and freezes into ice pellets. (Note: If the air is warm (above freezing) and the objects on the ground are cold, the rain falls, then freezes onto the objects on the ground.  This is called freezing rain.)

The cold air outside causes the window to become cold. The air near the window or glass also becomes cold (loses energy) and condenses on the glass. That's why the rear glass of cars have window heaters so that the glass warms up and makes the water on the glass become a gas again, thus no fog.

When we feel cold or frightened, tiny bumps causing a tingling sensation appear on our skin. Attached to each hair inside the skin is a tiny muscle. When you get scared or feel the cold, messages go shooting off from nerve endings that pick up the cold feeling. In a flash, signals come back to the muscles, and as a result each muscle gets taut. The skin around each hair also gets pulled up. The result is little bumps.

The warm front is moving into colder air. The moisture at the leading edge of the front freezes when it hits the cold air causing snow. As the front moves through, the warm air is increasingly higher in altitude which causes the falling moisture to warm up in the form of sleet then freezing rain then rain.\n\nHope this helps!

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.
