(2015-06)Este trabajo forma parte de una seria de investigaciones en perspectiva histórica-científica el impacto de los ciclones tropicales que han afectado a América Central, el Golfo de México y las Islas del Caribe. El interés ... -
Análisis del impacto del paso de los Ciclones Tropicales en el Mar Caribe sobre Costa Rica en las últimas décadas
(2009-03)El estudio de la actividad de los ciclones tropicales así como su caracterización histórica en la región centroamericana, es una prioridad para mitigar el impacto que estos fenómenos provocan en las diversas zonas del ... -
Aplicación de análisis multivariado al campo de anomalías de precipitación en Centroamérica
(1999-12)Because climate signals have components in different time and space scales it is difficult to identify the causes of climate variability when only one or a few stations are analyzed. Multivariate analysis of one or several ... -
Aplicación de un método de análisis de Fourier para sequencias temporales extremadamente largas: transformada discreta de 21 años de registro horario del nivel del mar en Quepos, Costa Rica

Aspects of climate variability during winter and summer in Central America
(2015-11-11)Climate variability during winter and summer in Central America is examined. In winter, we focused on the interaction between El Niño Southern Oscillation (ENSO), Pacific Decadal Oscillation (PDO), the Caribbean low-level ... -
Assessment of Central America Regional Climate Outlook Forum maps, 1998-2013
(2016)Starting 1997, the Regional Climate Outlook Forums or RCOFs have taken place in different Latin American countries, as an effort to generate climatic prediction products. “since 2000, the Forum is organized in Central ... -

Associations of decadal to multidecadal sea-surface temperature variability with Upper Colorado River flow
(2007-02)The relations of decadal to multidecadal (D2M) variability in global sea-surface temperatures (SSTs) with D2M variability in the flow of the Upper Colorado River Basin (UCRB) are examined for the years 1906- 2003. Results ... -
Associations of multi-decadal sea-surface temperature variability with US drought
(2008-09)Recent research suggests a link between drought occurrence in the conterminous United States (US) and sea surface temperature (SST) variability in both the tropical Pacific and North Atlantic Oceans on decadal to multidecadal ... -
Atmospheric forcing of cool subsurface water events in Bahía Culebra, Gulf of Papagayo, Costa Rica
