The water resources of the western United States depend heavily on snowpack to store part of the wintertime precipitation into the drier summer months. A well-documented shift toward earlier runoff in recent decades has been attributed to 1) more precipitation falling as rain instead of snow and 2) earlier snowmelt. The present study addresses the former, documenting a regional trend toward sma...

Altered precipitation regimes significantly affect ecosystem structure and function in arid and semi-arid regions. In order to investigate effects of precipitation changes on natural grassland community in the semi-arid Loess Plateau, the current research examined eco-physiological characteristics of two co-dominant species (i.e., Bothriochloa ischaemum and Lespedeza davurica) and community com...

reduced rainfall in many parts of the world have prompted scientists to try to manipulate, in different ways, to the nature, causing precipitation from accumulated water in the atmosphere. atmospheric ionization is a new method for producing precipitation and has attracted much attention. in this regard, in recent years, in some regions of the world, in different ways, the relation between mete...

In the present study, four high-resolution multi-sensor blended precipitation products, TRMM Multisatellite Precipitation Analysis (TMPA) research product (3B42 V7) and near real-time product (3B42 RT), Climate Prediction Center MORPHing technique (CMORPH) and Precipitation Estimation from Remotely Sensed Information using Artificial Neural Networks (PERSIANN), are evaluated over the Yangtze Ri...

This study examines the pattern and trend of seasonal annual precipitation along with extreme events in a data scare, south Asian country, Afghanistan. Seven indices were considered based on intensity, duration, frequency events. The revealed that Afghanistan is unevenly distributed at yearly scales. Southern southwestern provinces remain significantly dry whereas, northern northeastern receive...

STUDY OBJECTIVE To examine (i) the extent of illness caused by contamination of a waterworks with waste water due to overflow, and its correlation with precipitation; (ii) the potential secondary spread; (iii) economic losses due to sick leave. DESIGN A historical follow up study with structured postal questionnaires. SETTING A small community on the outskirts of greater Copenhagen at the e...

Determining the role of different precipitation periods for peak discharge generation is crucial for both projecting future changes in flood probability and for shortand medium-range flood forecasting. In this study, catchmentaveraged daily precipitation time series are analyzed prior to annual peak discharge events (floods) in Switzerland. The high number of floods considered – more than 4000 ...

Health of every living being is dependent on level pollutant in the environment, weather condition, etc, which are interrelated and influencing each other. Presence pollution particles high percentage such as particulate matter size 10 2.5 (PM10, PM25) microns creates higher risk lung functionality, respiratory disease reduces cardio functionality; also affects quality water sources. Rainfall, ...

Although bioleaching of chalcopyrite by thermophilic microorganisms enhances the rate of copper recovery, a high temperature accelerates iron precipitation as jarosite, which can bring many operational problems in the industrial processes. In this research work, the bioleaching of chalcopyrite concentrate by the thermophilic Acidianus brierleyi was studied, and the microbial grow...
