the effective patterns and mechanisms of synoptic systems during the wet and dry spells in midwest of iran(mwi) analyzed and discussed on seasonal scales from 1974 to 2003. synoptic analysis is based on synoptic chartson sea level pressure (slp), 850 and 500 hpa levels. the results of synoptic analysis show that dry spells in mwiare mostly corresponded to azores high (azh) intensifying and its ...

It is very important to analyze the performance of model rainstorm forecast for understanding intensity and position deviation precipitation improving ability. This paper uses classical scoring MODE (Method Object-Based Diagnostic Evaluation) method evaluate different products. The observation data used in article mainly include CMA (China Meteorological Administration) multi-source merged anal...

In recent years, dysfunction of hypothalamic-pituitary-adrenal (HPA) axis function has been implicated in a wide variety of psychiatric conditions. The importance of this system in responding to and coping with stress is well documented, and the integrity of such systems is of obvious significance to good mental health. The prefrontal cortex (PFC) is also heavily implicated in numerous psychopa...

During 6–7 June 2003, a Mei-Yu jet/front system over Southern China is characterized by appreciable horizontal temperature contrast below the 850 hPa level (>8 K), where cold, dry, postfrontal northeasterlies converge with warm, moist southwesterly flow, and above 400–hPa (>18 K) associated an upper-level front. The frontal baroclinic zone tilts northward slope of ~1/100. passage midlatit...

Extraordinary floods are linked with heavy rainstorm systems. Among various systems, their synoptic features can be quite different. The understanding of extreme rainstorms by causative processes may assist in flood frequency analysis and support the evaluation any changes occurrence magnitudes. This paper aims to identify most dominant meteorological factors for rainstorms, using ERA5 hourly r...

Abstract To investigate the relationship among summer atmospheric boundary layer (ABL) over Taklimakan Desert (TD), its land surface parameters and large scale meteorological field, Urumqi Institute of Meteorology China Meteorological Administration conducted a comprehensive observation in Tazhong, hinterland TD from July 1 to 31, 2016. The correlations between ABL height sensible heat, latent ...

The paper analyzes the influence of atmospheric circulation on cloudiness and cloud types during July August 2016 in Petuniabukta Svalbard-Lufthavn. For meteorological parameters, basic statistical measures were calculated average diurnal patterns analyzed. Taking data from reanalysis (NCEP/NCAR-The National Centers for Atmospheric Prediction/The Center Research) regarding mean sea-level pressu...
