A microburst is a local, intense downdraft which induces an outburst of damaging winds near the ground which extends 4 km or less. Microbursts are of interest to researchers because of the strong, occasionally damaging surface winds they produce, and the hazardous wind patterns they create for aircraft in the landing or takeoff phases of flight. The dynamics and aircraft hazards posed by an iso...

Abstract. The characterization of systematic forecast errors in lower-tropospheric winds is an essential component model improvement. This paper motivated by a global, long-standing surface bias the operational medium-range weather forecasts produced with Integrated Forecasting System (IFS) European Centre for Medium-Range Weather Forecasts (ECMWF). Over tropical oceans, excessive easterly flow...

the present article is a comparative research between z?r ceremony in south of iran (hormozgan province) and east africa (sudan). this research has been accomplished, based on the descriptive/exploratory methods, using library techniques and domain studies. people in these regions believe that human illnesses are caused by jins or satanic winds which penetrate in human body causing physical and...

Abstract. Isolated deep convective cloud life cycle and seasonal changes in storm properties are observed for daytime events during the US Department of Energy (DOE) Atmospheric Radiation Measurement (ARM) Green Ocean Amazon Experiment (GoAmazon2014/5) campaign to understand controls on behavior. Storm cycles documented using surveillance radar from initiation through maturity dissipation. Vert...

Recently, there has been a renewal of interest in the study of the effects of solar weather events on the ionization redistribution and irregularity generation. The observed changes at low and equatorial latitudes are rather complex and are noted to be a function of location, the time of the storm onset and its intensity, and various other characteristics of the geomagnetic storms triggered by ...

Abstract Heatwaves impose serious impacts on ecosystems, human health, agriculture, and energy consumption. Previous studies have classified heatwaves into independent daytime, nighttime, compound daytime-nighttime types, examined the long-term changes in three types. However, underlying mechanisms associated with variations different heatwave types remain poorly understood. Here we present fir...

Satellite observations have revealed a remarkably strong positive correlation between sea-surface temperature (SST) and surface winds on oceanic mesoscales of 10–1000 km. While this SST influence on the atmosphere had previously been identified from several in situ observational studies, its widespread existence in regions of strong SST gradients throughout the World Ocean and the detailed stru...

Introduction: Halvi is a traditional dairy product made from sheep milk in Mazandaran province, especially in the mountainous areas of Noor and Kojur. The fungus used in the preparation of Halvi is Auricularia auricula-judae. The present study aimed to investigate the chemical composition and microbiological properties of Halvi samples produced in various regions in No...

Abstract: To investigate possible seasonal patterns in water quality and plankton distribution, weekly samples were collected in a coral reef lagoon and in surrounding nearshore waters over a two year period. Additionally, two oceanographic surveys were also conducted in a larger area surrounding the primary study site during the seasonal extremes. The resulting information corroborated previou...
