1. Discuss the difference in the different fronts. (Stationary, warm, and cold) Including mid-latitude cyclones.

A front is a view of elements of air over a geographical area at a certain time. There are different kinds of fronts, stationary, warm or cool. A stationary front is a front between two air masses. These forces are quite equal and no front is strong enough to push the other one so it becomes stationary creating no warm or cool air. A warm front is a mass of air mostly of warm air. These move slower than the cold fronts and generally have little molecular movement. A cold front is an air mass with denser air molecules and cooler air. Weather front are also a reason for the formation of mid-latitude cyclones. Because of the different fronts interacting with each other, mid-latitude cyclones form and continue to be a weather maker in the mid-latitude regions.

2. How do clouds form and what are the characteristics of different cloud formations?

Cloud formation can occur in three different ways. One way in convection. Convection occurs when temperature throughout the day increase. The heat that warms surface is a basis of how they form. Orographic lift also creates the clouds. Orographic has to do with the terrain and mountains, for example mountain. The air traveling up a mountain creates orographic life and causes cloud formation at the top of mountain. Front can also cause cloud formation because two different fronts (warm and cold) interact and the result of this is cloud formation. Types of clouds that can form and are classified by how high up they are and they shape they appear in. High clouds are ones that appear the highest in the sky, generally above 16,500 ft. These types are prefixed with cirro-. Clouds that are high clouds include cirrus, which thin crystal like patterns. Cirrocumulus clouds are formed horizontally and maintain the thin crystal like pattern. Other types of clouds include stratocumulus which belongs...
