What is caused when warm air meets cold air?

Answer 1

When a warm air mass meets a cold air mass you have a frotal system, as stated above.

Rain occurs near the front. This rain occurs because the warm air rises over the cold air it is replacing (with a warm front). As the air rises it cools (but is still warmer than the air below it); the moisture in the air condenses and, eventually, falls as rain - in front of the "warm front"). With a cold front, the cold air wedges under the warm air, warm air rises etc. Here the rain occures behind the front.

With a front there is rain and a change of wind direction.

Answer 2

No Emerald. As you write, in a melancholy, the air rises, cools down with the help of the adiabatic results of a lesser tension aloft, and condensation produces clouds then, precipitations. It occurs everywhere around the low tension, not basically the warmth and chilly fronts. yet, at our latitudes (I stay in Norway) the depressions in many situations take place alongside the polar front the place temperate air meets polar one. the former being lighter climbs slowly over the less warm one. the adaptation between the chilly and the warmth front is that the latter is quite slack. Air rises slowly, giving place to first, misty climate, drizzle and later, rain. The chilly front is diverse. here, the polar chilly air comes from under and raise the temperature one. the front is lots steeper and it creates a much greater violent style of climate. collectively as the visibility will develop interior the polar dry and chilly air, the wind turns into greater gusty and the air is risky. It skill that the rain comes as showers and, each so often, thunderstorms. because of the fact the chilly front is lots steeper, it strikes swifter than the warmth one and, ultimately, advantageous properties terrain. whilst it meets the warmth one it turns into an occlusion front. There are 2 varieties of occlusions. If the polar air at the back of the front is less warm than the polar air only before it, then it lifts the whole heat front. it extremely is then referred to as a chilly occlusion. If the alternative, then the chilly front climbs over the warmth one and it extremely is termed a heat occlusion.

Answer 3

Air currents may be caused by differences in temperature, pressure, or impurity concentration. Temperature differences can cause air currents because warmer air is less dense than cooler air, causing the warmer air to appear "lighter." Thus, if the warm air is under the cool air, air currents will form as they exchange places. Pressure differences also cause air currents as the air flows from areas of higher pressure to areas of lower pressure. Impurities cause air currents due to entropy, which is the natural tendency of a system to move to a disordered state. For example, if perfume is sprayed in the corner of a closed room, it will eventually disperse evenly to the entire room.

Answer 4

Thunderstorms/ Electrical Storms.

Answer 5

Thunderstorms, electrical storms, Tornadoes.

Answer 6

A front. What kind of front depends on how they meet. Fronts can be warm, cold, occluded (both warm and cold) and quasi-stationary.

Answer 7

Thunderstorms/lightening and sometimes rain or tornados

Answer 8

It commonly called fog.

Answer 9

a storm of some kind

Answer 10

They shake hands and go to lunch.
