Deep learning has been successfully applied to precipitation nowcasting. In this work, we propose a pre-training scheme and new loss function for improving deep-learning-based First, adapt U-Net, widely-used deep-learning model, the two problems of interest here: nowcasting estimation from radar images. We formulate former as classification problem with three intervals latter regression problem...
The sustainability of a territory is closely related to its resources. Due climate change, the most precious natural resource, water, has been negatively affected by climatic conditions in terms quantity and quality. CLIMAT datasets 1 km2 spatial resolution were used processed ArcGIS environment generate maps actual evapotranspiration, water availability, effective precipitation for periods 196...
drought is transient phenomenon , slow , repetitive and integral part of the climate of each region. drought begins with a substantial reduction in precipitation over the long-term average rainfall and over time, reduced soil moisture and surface and ground water resources will continue to decrease. this phenomenon is the most important in bakhtegan basin because of its importance in strategic ...
the part of precipitation that directly meets the water requirements of a plant, is termed the effective rainfall. effective rainfall estimation methods consist of: direct measurement, empirical methods, and soil-water balance modeling. due to the high costs of measurements and storing devices such as lysimeter, empirical and balance methods are most commonly used to estimate the effective rain...
Forced precipitation of struvite (MgNH4PO4*6H2O) has been demonstrated to be an effective method to reduce dissolved reactive phosphorus (DRP) from swine manure. The development of a robust and flexible continuous flow struvite precipitation reactor is essential to the application of this method to modern livestock operations. Swine manure generally requires pH adjustment, magnesium amendment a...
The removal mechanisms of silicate using an aluminum hydroxide co-precipitation process was investigated and compared with an adsorption process, in order to establish an effective and validated method for silicate removal from wastewater. Adsorption isotherms, XRD and FT-IR analyses showed that silicate uptake occurred by adsorption to boehmite for initial Si/Al molar ratios smaller than two, ...
in this research, effect of north atlantic oscillation and sea surface temperature (sst) of atlantic ocean on precipitation and temperature of lorestan province and its effect on occurrence of drought and wet in this province were investigated. so, data of teleconnection indices used as an index for determination of fluctuations of pressure and sea surface temperature in atlantic ocean, amount ...
This study was down in Forest Park of Noor. In order to determination of tree ring response to climatic variations, 35 cores were taken from dominant natural stand of common ash (Fraxinus excelsior L.). The guide of this study was finding which climatic variables are effective in the ring width growth of ash in current growing year and previous years (one, two and three years before current g...
there are a number of ideas to generate cloud and precipitation in the southern coasts of caspian sea, but none of them explain the cause of precipitation particularly heavy and super heavy precipitations precisely. this study describes main thermodynamic factors when the situation and location of synoptic patterns are effective. on the basis of daily data, monthly regimes and monthly trends of...
