Ocean control of the breeding regime of the sooty tern in the southwest Indian Ocean [PDF]

, 2007
Food availability, which is often seasonal, is regarded as a key factor in the breeding success of seabirds. In oceanic tropical areas, the resources are mostly patchy and ephemeral at the surface, and the seasonality is less marked than at higher ...

Using microwave imager observations to improve the ocean temperature in a coupled NWP system

Quarterly Journal of the Royal Meteorological Society, EarlyView.
A recent upgrade to the ECMWF IFS has implemented outer‐loop coupling between the atmosphere and the ocean. This work uses this method to pass ocean skin temperature estimates derived from satellite‐borne microwave imagers to the ocean data assimilation system; the updated ocean state is then passed back to the atmospheric system.

On the diurnal ranges of Sea Surface Temperature (SST) in the North Indian Ocean [PDF]

, 2009
This paper describes the variability in the diurnal range of SST in the north Indian Ocean using in situ measurements and tests the suitability of simple regression models in estimating the diurnal range.

The physical and synoptic‐dynamical differences between warm days, hot days, and heatwaves during summer in Victoria, Australia

Quarterly Journal of the Royal Meteorological Society, EarlyView.
During the day, there is composite mean cold advection in the boundary layer on warm days (WDs), hot days (HDs) and heatwaves (HWs). There is weaker surface‐sensible heating on HDs and HWs. A nocturnal jet advects warm air on HDs and HWs. There is a strong and slow‐moving upper‐level anticyclone on HWs.

Subseasonal forecasts of the MJO and convectively coupled equatorial waves in ACCESS‐S2 and GraphCast: A multi‐year analysis

Quarterly Journal of the Royal Meteorological Society, EarlyView.
ACCESS‐S2 performs better in predicting longer time‐scale and slower moving waves (MJO and equatorial Rossby waves), while GraphCast performs better in predicting shorter and faster moving waves (Kelvin and mixed Rossby–gravity waves). However, both models systematically underestimate precipitation amplitude across all wave types, especially over the ...

Quantifying the Relative Contributions of the Global Oceans to ENSO Predictability With Deep Learning

Geophysical Research Letters
We propose a unified statistical method based on deep learning and heatmap analysis to quantify the relative contributions of the global oceans to El Niño–Southern Oscillation (ENSO) predictability. By incorporating subsurface signals in the Indian Ocean

Synoptic and large‐scale drivers of extreme precipitation events in the Himalayas

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Months associated with maximum frequency of extreme precipitation events (EPEs). 6102 extreme precipitation days (i.e., exceeding 99th percentile for daily precipitation) occurred across the Karakoram, Western Himalayas (WH), Central Himalayas (CH) and Eastern Himalayas (EH) during 1979 to 2023.

Assessment of subseasonal forecast skill of tropical–extratropical cloud bands over the four subtropical convergence zones

Quarterly Journal of the Royal Meteorological Society, EarlyView.
This study evaluates the subseasonal predictive skill of tropical–extratropical cloud bands across four subtropical convergence zones in ECMWF reforecasts (2003–2022). Results show that, while exact daily predictions are limited to one week, accounting for temporal displacement improves forecast skill significantly, revealing a systematic early onset ...

Carbon dioxide and nitrous oxide in the North Indian Ocean [PDF]

, 1995
The understanding of biogeochemical cycling of carbon dioxide and nitrous oxide in the oceans is essential for predicting the fate of antbropogenically emitted components.

Pola Arus Permukaan Pada Saat Kejadian Indian Ocean Dipole Di Perairan Samudera Hindia Tropis

, 2011
Indian Ocean Dipole in the Indian Ocean is a natural phenomenon that has interannual cycles. This research was conducted to understand the pattern of ocean surface currents in the waters of the Indian Ocean during Indian Ocean Dipole events.
