A unique feature of a comparative essay is that you have several different organizational strategies to choose from. 1  Use a traditional outline form if you would like to, but even a simple list of bulleted points in the order that you plan to present them would help.
A warm front is the transition zone in the atmosphere where an advancing warm subtropical, moist air mass replaces a retreating cold, dry polar air mass. On a weather map, a warm front is drawn as a solid red line with half-circles. The position of the half-circles shows the direction of frontal movement.
Cold Front - Cold air is overtaking warm air. Since cold air is denser than warm air, cold air undercuts a warm air mass. This produces a more concentrated line of heavy precipitation as the push of the cold air literally lifts the warm air just ahead of the front. This lifting of the air many times causes thunderstorms or very heavy showers.
