Explanation / Answer

Atmosphere distubadistu questions:

1. MP air masses from Atlantic Ocean are less important to the US than that of from Pacific Ocean because the mP airmasses reduce cold ocean currents whereas the mP air masses from the Atlantic from warmer fronts.

2. cold front is a transition zone where a cold air mass replaces a warmer air mass.Cold fronts usually move from northwest to southeast. Warm front is the vice versa to the cold front.

3. The storm starts to dissipates because the warm front will be overtaken by the cold front. As the two fronts get closer, the warm air becomes more aloft and itt is no longer in contact with Earth surface.
occluded front usually indicate the death of a midlatitude cyclone because it weakens the pressure gradient and shuts off the energy of the storm and air lifting mechanism and like this the cloud-producing mechanism and storm dies out.

4. Places Of latitudes between 30 and 60 degrees are affected.

5. The storm should develop over warm water. The water must be at least 80°F. The warm water provides the energy for increased evaporation of water from the ocean surface
