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.
A cold front extends to the south of the low pressure center, with a warm front to the east. Warm air is located ahead of the cold front and behind the warm front (the so-called warm sector), while cool air exists ahead of the warm front and cold air is present behind the cold front. Not all weather systems, however, are as simple as this model.
