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 warm front is the leading edge of a warmer air mass coming in to replace a cooler one. The general direction in which warm fronts move in North America is from the southwest to the northeast. Since the air temperature increases as a warm front moves in, the air mass is able to hold more moisture and thus brings warmer and more humid characteristics with it.
