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.
And especially during the winter months, the cold air that a warm front is attempting to displace is often heavy and dense and is stubborn to dislodge. As a result, the shape of some warm fronts end up contorted, seemingly looping around the colder air mass.
