the southern shores of caspian sea is subjected to several atmospheric factors due to its geographical position. north atlantic oscillation(nao) one of the effective phenomenon's affects the most part of hemisphere included caspian sea. in this research negative and positive phases of nao considered with variability of temperature and precipitation of southern shores of caspian sea in a 30...

The interannual variation of the Bowen ratio, through its effect on the warming extent of available energy to the ecosystem land surface air, heavily influences the ecosystem microclimate and affects the hydrological cycle at both regional and global scales. Although the precipitation amount in southeast China is not expected to change greatly as a result of climate change, the precipitation fr...

abstract obligatory modelling of precipitations in various periods, have a lot of problems and weakness because of their casual nature in time and space. moreover, their uncertainty in predictions, reduce credibility of estimations which have done via these models. wavelet is one of the novel and very effective methods in analyzing of time series and signals considered in the hydrology in recen...

1. Sodium salicylate modifies the precipitation of normal rabbit serum protein by sodium tungstate, and partially inhibits the precipitation of horse serum euglobulin by rabbit antiserum. Sodium salicylate added to a system containing crystalline egg albumin and its antibody partly prevents the formation of precipitate, the degree of inhibition being related to the concentration of salicylate. ...

Membrane based treatment processes are very effective in removing salt from wastewater, but are hindered by calcium scale deposit formation. This study investigates the feasibility of removing calcium from treated sewage wastewater using accelerated seeded precipitation. The rate of calcium removal was measured during bench scale batch mode seeded precipitation experiments at pH 9.5 using vario...

This study presents a novel technology, termed thermomorphic hydrophilicity base-induced precipitation (THBIP), for the effective removal of hardness ions from hypersaline brines with high-scaling propensity. THBIP utilizes thermoresponsive amine bases controlled scaling constituents in alkaline conditions and subsequently uses low-temperature heat to trigger phase separation aqueous solution, ...

Precipitation nowcasting is an important but hard problem. Currently, with the landing of deep learning, it has been treated as image prediction problem based on radar echo maps. However, learning models suffer from poor performance and blurred results. Lots improvement works enhance model by adding complex modules, which increases insufferable training memory time overhead. Others tempt to add...
