Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
A high pressure system (H) is moving to the southeast as shown on the weather map. Cold air is usually found north and west of a high pressure system. Warm air is to the south and east of the front. Based on this information, what is the best prediction for weather on the day after the system passes the point marked X?
A
wet air with cooler temperatures
B
Wet air with warmer temperatures
C
drier air with cooler temperatures
D
drier air with warmer temperatures
Explanation: 

Detailed explanation-1: -Lake-effect snow develops when cold, dry air, often originating from Canada, flows across the relatively warmer waters of the Great Lakes. As that cold air passes over the lakes, warmth and moisture from the water are picked up and transferred into the lowest portion of the Earth’s atmosphere.

Detailed explanation-2: -A weather front is a transition zone between two different air masses at the Earth’s surface. Each air mass has unique temperature and humidity characteristics. Often there is turbulence at a front, which is the borderline where two different air masses come together. The turbulence can cause clouds and storms.

Detailed explanation-3: -On the other hand, when a cold air mass catches up with a warm air mass, the cold air slides under the warm air and pushes it upward. As it rises, the warm air cools rapidly. This configuration, called a cold front, gives rise to cumulonimbus clouds, often associated with heavy precipitation and storms.

Detailed explanation-4: -Counterclockwise winds associated with cyclones transport heat and moisture from lower to higher latitudes and play a significant role in the movement of air masses.
