Abstract We present a climatological study of aerosols in four representative Caribbean Sea islands that is based on daily mean values aerosol optical properties for the period 2008–16, using depth (AOD) and Ångström exponent (AE) to classify dominant type. A assessment spatiotemporal distribution main types, their links with synoptic patterns, transport from different sources provided. Maximum...

This paper makes use of spaceborne observational data sets in order to characterize radiative processes involved spring time heat waves the Sahel. Spring corresponds hottest period year, with a high aerosol load, gradual moistening, and presence clouds contributing greenhouse effect. Heat are defined as synoptic events that have large spatial extent duration longer than 3 days. Two types studie...

In this study, the relationship between annual sunspot number (ASN) and annual precipitation totals (APT) has been investigated over the northern coasts of the Persian Gulf and Oman Sea by using two statistical methods: contingency tables and cross-correlation function. Only Bushehr and Jask stations (270 mm and 140 mm mean APT) have long term monthly precipitation records started instrumentall...

Extreme weather events such as ice storms cause significant damage to life and property. Accurately forecasting ice storms sufficiently in advance to offset their impacts is very challenging because they are driven by atmospheric processes that are complex and not completely defined. Furthermore, such forecasting has to consider the influence of a changing climate on relevant atmospheric variab...

introduction one of the important events that usually occur in seas and large water bodies’ concurrent with the change of season is the growth and species increase of phytoplankton. in the natural environment, this event does not result in imbalances of water ecosystems. however, pollution caused by human activities results in excessive growth and reproduction of phytoplankton and other opportu...

Temperature, humidity and precipitation in an area, are parameters proved influential in the climate of that area, and one should recognize them so that he can determine the climate of that area. Climate changes are of primary importance in climatology, and in recent years, have been of great concern to researchers and even politicians and organizations, for they can play an important role in s...

A new set of averaging rules is put forward that exactly determines the means of air temperature, mixing ratio, and velocity by incorporating weighting factors in accordance with physical conservation laws. For the temperature and velocity, respectively, the means calculated according to these rules are shown to be in accordance with the gas law and the most fundamental definition from classica...

The micro-scale and meso-scale ocean dynamic processes which are nonlinear and have large variability, have a significant impact on the fisheries, natural resources, and marine climatology. A rapid, refined and sophisticated observation system is therefore needed in marine scientific research. The maneuverability and controllability of mobile sensor platforms make them a preferred choice to est...
