Regional Precipitation Study in Central America, Using the WRF Model
(Examensarbete vid Institutionen för geovetenskaper, pp.1-45, 2012)
Using the regional climate model WRF, and the NCEP-NCAR Reanalysis Project data as boundary and initial conditions, regional precipitation was estimated by means of the dynamical downscaling technique for two selected ...
Smiling in the rain: Seven reasons to be positive about uncertainty in hydrological modelling
(Processes Hydrological Processes Vol. 27(7): 1117–1122, 2012-03-30)
Over 20 years ago, the notion of ‘positive uncertainty’ was introduced in the field of psychology (Gelatt, 1989). This was coincident to some developments in the hydrological sciences (e.g. Beven and Binley, 1992; Grayson ...
Evaluación del método FAO-56 en Costa Rica
(2014-12)
El Tanque evaporímetro tipo A es el único registro de datos utilizable para evaluar un modelo de evapotranspiración en Costa Rica. Inicialmente se calcula la evapotranspiración utilizando el modelo FAO-56 para un cultivo ...
Potential increase in floods in California’s Sierra Nevada under future climate projections
(2011-12)
California’s mountainous topography, exposure to occasional heavily moisture-laden
storm systems, and varied communities and infrastructures in low lying areas make it highly
vulnerable to floods. An important question ...
The Caribbean Low-Level Jet, the Inter-Tropical Convergence Zone and Precipitation Patterns in the Intra-Americas Sea: A Proposed Dynamical Mechanism
(2015-01-12)
Data from the Global Precipitation Climatology
Project covering Central America, the Caribbean Sea, the
eastern tropical Pacific and northern South America are used
to compute four indexes that describe characteristics ...
Attribution of Declining Western U.S. Snowpack to Human Effects
(2008-12-01)
Observations show snowpack has declined across much of the western United States over the period 1950–99. This reduction has important social and economic implications, as water retained in the snowpack from winter storms ...
Utility of daily vs. monthly large-scale climate data: an intercomparison of two statistical downscaling methods
(2008-03-13)
Downscaling of climate model data is essential to local and regional impact analysis. We compare two methods of statistical downscaling to produce continuous, gridded time series of precipitation and surface air temperature ...
The utility of daily large-scale climate data in the assessment of climate change impacts on daily streamflow in California
(2010-06-30)
Three statistical downscaling methods were applied to NCEP/NCAR reanalysis (used as a surrogate for the best possible general circulation model), and the downscaled meteorology was used to drive a hydrologic model over ...
Southern California and the perfect drought: Simultaneous prolonged drought in southern California and the Sacramento and Colorado River systems
(2008-09-01)
Southern California relies heavily upon imported water from the Sacramento and Colorado river systems to augment local supplies and to mitigate the impacts of drought. In this paper a ‘perfect drought’ is defined as a ...
Cálculo de la evaporación en Costa Rica mediante el método FAO-56
(2014-06)
Con el método FAO-56 se calcula la evapotranspiración de referencia para un cultivo de referencia “De una altura de 0,12m con una resistencia superficial de 70 s/m y un albedo de 0,23”. Posteriormente se calcula el coeficiente ...
