Sampling strategies and four-dimensional assimilation of altimetric data for ocean monitoring and prediction [PDF]
, 1984 Numerical experiments using simulated altimeter data were conducted in order to examine the assimilation of altimeter-derived sea surface heights into numerical ocean circulation models. A reduced-gravity, primitive equation circulation model of the Gulf

Spatiotemporal Changes in Precipitation Concentration in the Atlantic‐European Region
International Journal of Climatology, EarlyView.This study analyses changes in precipitation concentration using ERA5 and E‐OBS datasets. Gini index as a measure of precipitation concentration revealed a gradual expansion of areas with increasing unevenness in precipitation distribution across the Atlantic‐European region since 1961.

Effects of Dipole Eddies on Acoustic Propagation in the Northeastern South China Sea
Ocean-Land-Atmosphere ResearchMesoscale eddies can greatly influence underwater acoustic propagation, which holds substantial academic and practical importance. The impacts of individual cyclonic eddies (CEs) or anticyclonic eddies (AEs) on acoustic propagation have been reported in ...

Sunshine Duration in Brazil From Meteosat (1983–2020): Climatology, Variability and Long‐Term Trends
International Journal of Climatology, EarlyView.Using nearly four decades of Meteosat satellite data (1983–2020), this study presents a country‐wide climatology of sunshine duration (SDU) in Brazil. The results reveal marked regional contrasts, dominant modes of variability, and significant long‐term trends, providing new information on the most relevant meteorological systems that influence SDU and

Projected Annual and Monsoonal Precipitation Trends of CMIP6 Over Peninsular Malaysia
International Journal of Climatology, EarlyView.In this study, we examined historical and projected precipitation temporal trends across Peninsular Malaysia using ground‐based records and CMIP6 models from NEX‐GDDP. Analysing data from 518 reliable gauges over 1973–2022, it identified spatial and monsoonal variations.

Quantifying the Role of Oceanic Feedbacks on ENSO Asymmetry
Geophysical Research Letters, 2019 The role of oceanic feedbacks in determining the asymmetry of El Niño–Southern Oscillation (ENSO) magnitude, spatial structure, and duration is quantified on the basis of a novel temperature variance budget.
