Abstract:
The aim of the present study is the study of the most important features of temporal variation of the clouds’ types over Magurele area (44.35°N, 26.03°E)in Romania, during 2009 and 2010. The monthly variations of cloud’s types was performed for April and July in warm season, and for October and January in cold season. The daily observational data from ceilometer and the coincident daily satellite data from MODIS system were used in study. The satellite data allowed the determination of some important parameters for the microstructure of the clouds: temperature at the top of the cloud, effective cloud range, water content and optical thickness. These parameters were used in the International Sattelite Cloud Climatology Project (ISCCP) model to classify the cloud on their heights. The maximum of occurrences is in the case of high clouds readily accessible to the satellite detection while in the case of the ceilometer detection the number of the case of lower cloud occurrence is higher. The satellite data shows that the maximum optical thickness values correspond to the vertical growth clouds in January for both 2009 and 2010, while the ceilometer data shows the maximum optical thickness correspond to April 2009 and 2010 for stratocumulus clouds. The results regarding the cloud types are correlated with the high precipitation amounts in these two months.
