A Multivariate Regression Model Between the October Rainfall Anomalies in Central America and the Tropical Pacific and Atlantic Ocean
(1999-11)
Principal Component Analysis was used to identity common anomaly patterns amongst 72 rainfall gauge stations in Central America during October, in order to identify stations to from October Rainfall Indices. October was ...
Tropical Intraseasonal Modes of the Atmosphere
(Reviews In Advance. vol 39: 5.1–5.27, 2014-08-06)
Tropical intraseasonal variability (TISV) of the atmosphere describes the coherent variability in basic state variables, including pressure, wind, temperature, and humidity, as well as in the physical phenomena associated ...
Variabilidad interanual y estacional de la atmósfera libre sobre Costa Rica durante eventos de El Niño
(2001)
Con base en una técnica de composición de anomalías de los campos meteorológicos considerados, se diagnosticaron las principales alteraciones climáticas de la atmósfera libre sobre Costa Rica durante los eventos de El Niño, ...
Cuenca del Río Arenal: Análisis de los eventos La Niña 1988-89 y 1996
(2000)
The precipitation patterns during La Niña events of 1988-89 and 1996 are analyzed for the Arenal River Basin. Pentad data are used to study the rainfall distribution for Naranjos Agrios (in the northwestern part of the ...
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 ...
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 ...
EL ENOS, el IOS y la corriente en chorro de bajo nivel en el oeste del Caribe
(2000)
Using Southern Oscillation Index (SOI) data from 1900-1997 and some other shorter SOI series before 1900, it is determined through filtering and basic statistics, the duration of the warm/cold phases of the events associated ...
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 ...
Medición y cálculo del índice ultravioleta en Costa Rica
(2014-12)
Este trabajo de investigación pretende hallar una técnica para estimar los valores del índice ultravioleta, con los datos medidos de la radiación solar ultravioleta-B (UV-B) para San José, Costa Rica. El índice ultravioleta ...
