A Generalized Study of Precipitation Forecasting
نویسندگان
چکیده
Proceeding on a purely physical basis, Thompson and Collins employed in their pilot study observed winds to compute divergence over a triangular area in the Midwest. From this divergence vertical motion was then derived using continuity considerations and, with observed moisture, was used to compute the average rate of precipitation over the area. Their procedure was completely numerical and designed for either hand or machine computation, requiring only the wind and RAOB data obtained from soundings at the vertices of the triangle. Effects of subjective analysis of the data were thus purposely eliminated.

Probabilistic Precipitation Forecasting Based on Ensemble Output Using Generalized Additive Models and Bayesian Model Averaging
A probabilistic precipitation forecasting model using generalized additive models (GAMs) and Bayesian model averaging (BMA) was proposed in this paper. GAMs were used to fit the spatial-temporal precipitation models to individual ensemble member forecasts. The distributions of the precipitation occurrence and the cumulative precipitation amount were represented simultaneously by a single Tweedi...
متن کاملForecasting of rainfall using different input selection methods on climate signals for neural network inputs
Long-term prediction of precipitation in planning and managing water resources, especially in arid and semi-arid countries such as Iran, has a great importance. In this paper, a method for predicting long-term precipitation using weather signals and artificial neural networks is presented. For this purpose, climatic data (large-scale signals) and meteorological data (local precipitation and tem...
متن کاملForecasting of Groundwater Table and Water Budget under Different Drought Scenarios using MODFLOW Model (Case Study: Garbaygan Plain, Fars Province, Iran)
Groundwater drought is a natural hazard that develops when groundwater systems are affected by climatical drought, when climatical drought occures, first groundwater recharge, later groundwater levels and groundwater discharge decrease. The origin of drought is a deficit in precipitation and that takes place in all the elements that comprise the hydrological cycle (flow in the rivers, soil mois...
متن کاملSynoptic approach to forecasting and statistical downscaling of climate parameters (Case study: Golestan Province)
The present study attempts to introduce a method of statistical downscaling with a synoptic view. The precipitation data of Golestan Province has been used for the years 1971 to 2010. Employing multivariable regression, this study models the precipitation gauges in the station scale, by making use of 26 predicting components of model HadCM3, on the basis of two A2 and B2 scenarios. However, the...

Floods are among the natural disasters that cause human hardship and economic loss. Establishing a viable flood forecasting and warning system for communities at risk can mitigate these adverse effects. However, establishing an accurate flood forecasting system is still challenging due to the lack of knowledge about the effective variables in forecasting. The present study has indicated that th...
