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 ...
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 ...
Climatología de la Atmósfera Libre sobre Costa Rica
(2001)
A partir de una serie de tiempo de datos aerológicos, de 1972 a 1989, se obtuvo una climatología de la atmósfera libre sobre Costa Rica, con el propósito de actualizar un estudio previo (Grandoso et al., 1981) y poder ...
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 ...
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 ...
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 ...
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 ...
Balanced dynamics of deep and shallow Hadley circulations in the tropics
(Journal of Advances in Modeling Earth Systems 6(3): 777-804, 2014-05-06)
This paper examines the dynamics of large-scale overturning circulations in the tropical atmosphere using an idealized zonally symmetric model on the equatorial b-plane. Under certain simplifications of its coefficients, ...
Cuenca del Río Arenal: Análisis de los eventos Niño de los años 1992-93, 1994-95 y 1997-98
(2000)
The precipitation patterns during El Niño events of 1992-93, 1994-95 and 1997-98 are analyzed for the Arenal River Basin. Pentad data are used to study the rainfall distribution for Naranjos Agrios (in the northwestern ...
