Haze is caused by solid particles being trapped at low levels, requiring a stable atmosphere (such as an inversion) so air cannot rise. As you may have discovered when driving a car, haze is particularly problematic when it is combined with a low sun in the direction you are driving - so to the east in the morning when the sun rises, and to the west in the evening when the sun sets.
