Changes of microclimate in a sedge-grass marsh within the last 40 years
Dušek, Jiří ; Stellner, Stanislav ; Hudecová, S.
The average, maximum and minimum air temperatures have been gradually increasing since 1977 to 2017. The air temperature rise was not the same in all periods of the year. We found different increases for individual months. The daily mean air temperature rose significantly in the growing period (April-August). The precipitation characteristics have been changing in the sedge-grass marsh too. The observed trends differ among months in sign as well as in the magnitude, and they are consistent with the air temperature changes. We found that extreme precipitation seems to occur significantly more frequently in recent years compared to the period before 2000. Awareness of these changes is important for possible positive human intervention when a desirable wetland ekosystem function is threatened.\n
