Long Term Monitoring and Connection between Topography and Cloud Cover Distribution in Serbia

Abstract

The use of weather satellite recordings has been growing rapidly over the last three decades. Determining the patterns between meteorological and topographical features is an important scientific job. Cloud cover analysis and properties can be of the utmost significance for potential cloud seeding. Here, the analysis of the cloud properties was conducted by means of Moderate Resolution Imaging Spectroradiometer (MODIS) satellite recordings. The resolution of used data was 1 km2 within the period of 30 years (1989–2019). This research showed moderate changing of cloudiness in the territory of Serbia with a high cloudiness in February, followed by cloudiness in January and November. For the past three decades, May has been the month with the highest cloudiness. The regions in the east and south-west, and particularly in the west, have a high absolute cloudiness, which is connected with the high elevation of the country. By means of long term monitoring, the whole territory of Serbia was analyzed for the first time, in terms of cloudiness. Apart from the statistical and numerical results obtained, this research showed a connection between relief and clouds, especially in the winter season. Linear regression MK (Mann–Kendall test) has proven this theory right, connecting high elevation sides with high absolute cloudiness through the year.

Assessment of Seasonal Variability of Extreme Temperature in Mainland China under Climate Change

“…Furthermore, radiation is greatly affected by cloud cover, which is very important for agricultural production, crop distribution, and animal migration. With climate change, global cloudiness has also changed significantly [71][72][73][74]. Limited by space, this article only analyzed the seasonal trend of extreme temperature in mainland China and did not assess the impact of the trend on the crop yield, especially rice, maize, and wheat.…”

Variability of the Southwestern Patagonia (51°S) Winds in the Recent (1980–2020) Period: Implications for Past Wind Reconstructions

“…These winds are responsible for the heat transport from the mid-latitudes towards the poles following undulating stationary paths [5]. Because of the topography of southern Patagonia, SWWs control the cloud cover and rainfall on the leeside of the Andes, which means that the cloud cover is strongly correlated wind speed (supplementary materials Figure S1) on the western side of the Andes [15,16].…”

GIS application in analysis of threat of forest fires and landslides in the Svrljiski Timok basin (Serbia)

“…Ради бољег приказа угрожености терена, географски информациони системи (ГИС) нашли су велику примену у савременим истраживањима. Моделовање података у ГИС представља ефикасан и поуздан алат за израчунавање и опис података о ефектима потенцијалних опасности (Gheshlaghi et al, 2020;Parajuli et al, 2020;Valjarević et al, 2021). Циљ рада јесте да обрадом природних и антрпопогених услова прикаже и издвоји подручја у сливу која су врло осетљива на појаву шумских пожара и клизишта.…”

“…In order to better represent the terrain endangerment, GIS has found major application in modern research. Data modeling in geographic information systems is a powerful tool for calculating and describing data on the effects of potential risks (Gheshlaghi et al, 2020;Parajuli et al, 2020;Valjarević et al, 2021). The purpose of the paper is to present and segregate areas in the basin that are very sensitive to the occurrence of forest fires and landslides by processing natural and anthropogenic conditions.…”
