Sounding

 

For an analysis of the vertical profile of the atmosphere, soundings from two locations were used: Belgrade (203m) and Szeged (83m). Low-level temperature inversion formed by cooling of the surface by intensive overnight Earth's radiation can be seen in Figure 2.2 (left). It should be stressed that the Belgrade sounding station's location is not representative for the city parts with lower altitudes, Figure 2.2 (right). Also, it can be noticed that humidity at the surface is too low for fog formation.

The next day when the fog lifted, stratus formed (Fig. 2.3 and 2.4).
