Why the orange trees are often sprayed with water?

Although it is grossly counter-intuitive, whenever citrus groves are in risk of experiencing below-freezing temperatures, the trees are sprayed with water. This causes frost to form on the rinds of the fruit and gives an extra layer of insulation against the low temperatures that would or else freeze the edible portion of the fruit and obliterate the crop.
