This study revisits the question posed by Hoskins on why the Northern Hemisphere Pacific sea level pressure (SLP) anticyclone is strongest and maximally extended in summer when the Hadley cell descent in the northern subtropics is the weakest. The paradoxical evolution is revisited because anticyclone buildup to the majestic summer structure is gradual, spread evenly over the preceding 4–6 mont...
Abstract Seasonal and interannual variations of chlorophyll- a (chl- ) in the upper Gulf Thailand (uGoT) were obtained using new regionally tuned algorithms applied to Moderate Resolution Imaging Spectroradiometer-Aqua. This long time-series (2003–2017) data analyzed context environmental conditions associated with Southeast Asian Monsoon. Chl- distribution patterns distinct for non-monsoon (NO...
Abstract As an internal forcing of the earth climate system, soil moisture (SM) significantly influences water and energy cycle by controlling evapotranspiration terrestrial solar energy. The current study used observed precipitation, remotely sensed SM, reanalysis atmosphere land parameters to assess East Asian Monsoon (EAM) precipitation variability due meridional SM oscillations across China...
the west of esfahan province, iran, is one of the most important agricultural areas throughout the country due to the climate variability and life-giving water of zayanderood river. rice is one of the major and economic crops in this area. the most important climatic elements in agricultural activities which should be considered include temperature, relative humidity, precipitation and wind. so...
abstract: proverbs are of the language materials which of the food of any language depends on the quality and quantity of these same materials. in the present research, the researcher tried to present the ramsarian proverbs according to four variables of color, fruit, plantsand animals that selected from the book of the members of each of these four variables, put them into the spss system fo...
We examined changes in several independent intensity indices of four major tropical monsoonal circulations for the period 1950–1998. These intensity indices included observed land surface precipitation and observed ocean surface pressure in the monsoon regions as well as upperlevel divergence calculated at several standard levels from the NCAR/NCEP reanalysis. These values were averaged seasona...
Water vapor in the lower stratosphere exhibits localized maximum values during Northern Hemisphere summer in the Asian and North American (NA) monsoon regions. The processes maintaining these maxima are not well understood. We analyze the variability of water vapor in the monsoon regions based on Aura Microwave Limb Sounder satellite observations during 2005–2013 and quantify links to deep conv...
heavy rains are one of the features of arid and semi arid climates which result in flood. this kind of rainfall originates from environmental and synoptic conditions. mediterranean cyclones are the major factor in heavy rainfall in iran, but these cyclones do not happen in some parts of iran such as southern and southeastern areas. in this study, it has been tried to pinpoint the synoptic reaso...
peace and national security protection and ironic solving of international conflicts become the preliminary foundation of the united nations charter and had been considered as the main responsibilities of the security council, after world war ii and the establishment of united nations organization. therefore, the security council enables to analyze every kind of conflicts and challenges which ...
in new management approaches, in the organizations with inflexible structure, existing of red tapes and interruptions caused by limitations and also non-compliance with environmental changes, create demotivation among staff. with regard to the influence of job motivational potential and its relationship to the type of organizational structure( enabling and dissuasive), the goal of this research...
