A theoretical model of strong and moderate El Niño regimes
(Springer, 2019-06-01)
The existence of two regimes for El Niño (EN) events, moderate and strong, has been previously shown in the GFDL CM2.1 climate model and also suggested in observations. The two regimes have been proposed to originate from ...
Evidence of nonlinear Walker circulation feedbacks on extreme El Niño Pacific diversity: observations and CMIP5 models
(Wiley, 2021-04)
The Walker circulation (WC) is essential for the formation and diversity of El Niño events. However, the nonlinear WC feedback during extreme Central and Eastern El Niño episodes (C and E episodes, respectively) has received ...
Diversity of moderate El Niño events evolution: role of air–sea interactions in the eastern tropical Pacific
(Springer, 2019-06)
In this paper we investigate the evolution of moderate El Niño events during their developing phase with the objective to understand why some of them did not evolve as extreme events despite favourable conditions for the ...
Strong and moderate nonlinear El Niño regimes
(Springer, 2016-03)
It has been previously proposed that two El Niño (EN) regimes, strong and moderate, exist but the historical observational record is too short to establish this conclusively. Here, 1200 years of simulations with the GFDL ...

Índices locales del ciclo El Niño Oscilación del Sur para las regiones naturales de Colombia
(Universidad Nacional de ColombiaBogotá - Ciencias - Maestría en Ciencias - MeteorologíaDepartamento de GeocienciasFacultad de CienciasBogotáUniversidad Nacional de Colombia - Sede Bogotá, 2021-03-15)
Se definieron índices locales del ciclo de El Niño Oscilación del Sur (ENOS) en las regiones naturales de Colombia. Se utilizaron datos de temperatura del aire (Ta) y precipitación (Pr) para el periodo 1971-2015 en 14 ...
Looking for a physical basis of rainfall multifractality
(Departamento de Geociencias y Medo AmbienteUniversidad Nacional de Colombia - Sede Medellín, 2019-12-18)
The study of rainfall arises from the necessity for knowing large and short-term climatic dynamics, as well as their affectations in the context of engineering practices. This research focus on the study of tropical rainfall ...
