 Zs. Magyari-Sáska

ABSTRACT - The present study aims do describe the fog phenomena in the Upper Mures Basin and an analysis of the persistence of fog in the region. The data source is NCDC, comprising data about fog occurence,average daily visibility, as well as daily minimum temperatures. The study includes both a descriptive statistics of the phenomena and a part of frequantial analysis. The descriptive statistics succeeds in identifying the valley fog in the area as being typical to the winter months. The frequential analysis targets both detecting the number of days with fog in the area with a visibility under 1000 m, as well as the number of consecutive days in which the mean daily visibility is under 1000 m. The result of this analysis is the statement that, in the long run, the proportion of consecutive days having a visibility under 1000m with respect to the numer of days with visibility under 1000m is around 40% at Joseni and approximately 80% for Toplita.
