Multisite downscaling of daily precipitation with a stochastic weather generator
Stochastic models of daily precipitation are useful both for characterizing different precipitation climates and for stochastic simulation of these climates in conjunction with agricultural, hydrological, or other response models. A simple stochastic precipitation model is used to downscale— i.e. disaggregate from area-average to individual station—precipitation statistics for 6 groups of 5 U.S...
متن کاملA new precipitation and drought climatology based on weather patterns
Weather-pattern, or weather-type, classifications are a valuable tool in many applications as they characterize the broad-scale atmospheric circulation over a given region. This study analyses the aspects of regional UK precipitation and meteorological drought climatology with respect to a new set of objectively defined weather patterns. These new patterns are currently being used by the Met Of...
متن کاملA daily weather generator for use in climate change studies
This paper describes the development of a weather generator for use in climate impact assessments of agricultural and water system management. The generator produces internally consistent series of meteorological variables including: rainfall, temperature, humidity, wind, sunshine, as well as derivation of potential evapotranspiration. The system produces series at a daily time resolution, usin...
متن کاملCirculation weather types and spatial variability of daily precipitation in the Iberian Peninsula
*Correspondence: Alexandre M. Ramos, Faculdade de Ciências, Instituto Dom Luiz, Universidade de Lisboa, Campo Grande, Edf. C8, Piso 3, Sala 8.3.1, 1749-016 Lisboa, Portugal e-mail: [email protected] The relationships between atmospheric circulation patterns and daily Iberian rainfall are here explored at high spatial resolution (0.2◦) using the Jenkinson and Collison automated classification sch...
متن کاملEstimating IDF based on daily precipitation using temporal scale model
The intensity –duration –frequency (IDF) curves play most important role in watershed management, flood control and hydraulic design of structures. Conventional method for calculating the IDF curves needs hourly rainfall data in different durations which is not extensively available in many regions. Instead 24-hour precipitation statistics were measured in most rain-gauge stations. In this stud...
