Types of Clouds Common in Cluj-Napoca

Cluj-Napoca experiences an array of cloud types throughout the year, each with its distinct characteristics and meteorological significance. One of the most prominent cloud types is the cumulus cloud. These puffy, cotton-like clouds often appear in fair weather and are associated with low-level convective activity.

Stratus clouds are associated with low-pressure systems and stable atmospheric conditions. When stratus clouds persist for several days, they can result in extended periods of overcast skies and gloomy weather. Conversely, cirrus clouds are thin, wispy clouds that form in the high atmosphere. Composed primarily of ice crystals, cirrus clouds are often visible on fair-weather days and indicate the presence of high-altitude moisture.
