Spatiotemporal Evolution of Hydroclimatic Variables in the Brazilian Semi‐Arid Region Through the Aridity Index and Susceptibility to Desertification

open access: yesInternational Journal of Climatology, EarlyView.
Over the past 60 years, noticeable changes have been observed in the main hydroclimatological variables, driven by both natural and anthropogenic factors. In the context of climate change, such behaviour may adversely affect the state's economic activities, as well as increase the recurrence of extreme events in the region.

Evaluating drought events under influence of El-Nino phenomenon: A case study of Mekong delta area, Vietnam

open access: yesJournal of Agrometeorology, 2018
The spatio-temporal variability of meteorological droughts in the Mekong delta area of Vietnam were analysed to detect drought events using the standardized precipitation index (SPI) at different time scales based on 32-year (1984-2015) monthly rainfall

Tropical Atmospheric Circulations: Dynamic Stability and Transitions

open access: yes, 2009
In this article, we present a mathematical theory of the Walker circulation of the large-scale atmosphere over the tropics. This study leads to a new metastable state oscillation theory for the El Nino Southern Oscillation (ENSO), a typical inter-annual ...

Multi‐Country‐Multi‐City Characterisation of Heat Stress and Exposure in Africa

open access: yesInternational Journal of Climatology, EarlyView.
This study provides the first continent‐wide, grid‐specific assessment of heat stress trends in Africa, revealing a sharp rise in multi‐scale extreme heat episodes and shifting population exposure. Findings highlight urgent implications for urban planning and climate adaptation.

El Niño ─ related precipitation variability in Perú [PDF]

open access: yesAdvances in Geosciences, 2008
The relationship between monthly mean sea surface temperature (SST) anomalies in the commonly used El Niño regions and precipitation for 44 stations in Perú is documented for 1950–2002.

Regulation of primary production in the Gulf of California through interaction of large-scale and local ocean processes [abstract] [PDF]

open access: yes, 1988
EXTRACT (SEE PDF FOR FULL ABSTRACT): The suppression of primary productivity observed in eastern boundary ecosystems of the Pacific during El Nino episodes does not occur throughout the Gulf of California.

Migration of atmospheric convection coupled with ocean currents pushes El Nino to extremes [PDF]

open access: yes
The warm phase of El Nino-Southern Oscillation can grow much stronger than the cold phase, but the associated dynamics are not well understood. Here we show that the anomalous zonal advection of warm water is the major process that pushes El Nino to ...

Addressing the World War 2 Warm Anomaly in HadSST.4.2.0.0

open access: yesInternational Journal of Climatology, EarlyView.
We present an update to the Hadley Centre Sea‐Surface Temperature dataset (HadSST.4.2.0.0) that addresses residual warm bias during the Second World War (WW2). Using a quantitative definition of the WW2 warm anomaly we identify Engine Room Intake (ERI) bias corrections as the dominant factor in HadSST4, and use this to propose new constraints on ERI ...

Analysis of rainfall over northern Peru during El Nino: A PCDS application [PDF]

open access: yes
In an examination of GOES satellite data during the 1982 through 1983 El Nino period, the appearance of lee wave cloud patterns was revealed. A correlation was hypothesized relating an anomalous easterly flow across the Andes with the appearance of these
