Meteorology over coastal region is a driving factor to the concentration of air particles and reactive gases. This study aims conduct research determine level year-round interaction meteorological factors with particle number mass in 2018, which moderately influenced by Southeast Asian haze. We obtained measurement data for count (PNC), mass, gases, from Global Atmospheric Watch (GAW) station l...
Multiple intertidal bar (MITB) beach systems comprise a succession of subdued, shore-parallel sandbars, developed under low-energy conditions in meso- to macrotidal settings. Their relatively stable morphologies over long timescales are commonly attributed dynamic equilibrium, driven primarily by seasonal morphodynamics. The behaviour is, however, poorly understood. relationship between tempora...
The phylogeny of the superfamily Chirostyloidea (Decapoda: Anomura) has been poorly understood owing to limited taxon sampling and discordance between different genes. We present a nine-gene dataset across 15 chirostyloids, including all known yeti crabs (Kiwaidae), to improve the resolution of phylogenetic affinities within and between the different families, and to date key divergences using ...
Synoptic analysis of the torrential on Day 21, 1398 (Case study: Zahedan and Qeshm) Abstract Rainfall is the most important phenomenon or feature of the environment and so far many studies have been done about its causes. In any place, rainfall occurs when humid air and climbing cause are provided. Both of these conditions are provided by the circulation pattern. The study area is affe...
1-Interoduction: Air pollution has been considered as one of the global challenges. According to world health organization (WHO), dust particles are the 5th most dangerous cause of death 4.2 million in the world. According to the world meteorological organization (WMO), when the wind speed increases more than 15 m/s and the visibility decreases because of dust particles less than 1 km, it is c...

This study evaluates and quantifies the variation in vegetation, plant nutrients, and microclimate across four topographic aspects in an Appalachian watershed (398399430N, 798459280W). The study found that the north and east aspects were 27–50% more productive than the west and southwest aspects. Species groups that showed strong aspect preference included yellow poplar (Liriodendron tulipifera...
This study was aimed to investigate the direction and magnitude of soil organic carbon (SOC) dynamics and the underlying mechanisms following agricultural abandonment in a subtropical karst area, southwest China. Two post-agriculture succession sequences including grassland (~10 years), shrubland (~29 years), secondary forest (~59 years) and primary forest with cropland as reference were select...
Consistency and trend in the Northeast and Southwest monsoon rainfall of Tamil Nadu have been studied utilizing the data for the 60-year period from 1941 to 2000. It is seen that both the Northeast and Southwest monsoon rainfall of Tamil Nadu is consistent in double mass curve analysis method. Frequency distribution of Northeast and Southwest monsoon rainfall of Tamil Nadu is normal. Decreasing...
Two sediment records of dust deposition from Fish Lake, in southern Colorado, offer a new perspective on southwest United States (Southwest) aridity and dustiness over the last ~3000 years. Micro scanning X-ray fluorescence and grain size analysis provide separate measures of wind-deposited dust in the lake sediment. Together these new records confirm anomalous dustiness in the 19th and 20th ce...
