Vertical distribution of chlorophyll in dynamically distinct regions of the southern Bay of Bengal [PDF]

, 2019
The Bay of Bengal (BoB) generally exhibits surface oligotrophy, due to nutrient limitation induced by strong salinity stratification. Nevertheless, there are hot spots of high chlorophyll in the BoB where the monsoonal forcings are strong enough to break

An opportunity index to anticipate when subseasonal predictions are useful

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Simultaneously active subseasonal windows of forecast opportunity can be combined into a single opportunity index, which can be used operationally to anticipate enhanced or reduced subseasonal prediction skill. For predictions of temperature anomalies in Switzerland during summer—a region and season with particularly low predictability—skill can nearly

The surface diurnal warm layer in the Indian Ocean during CINDY/DYNAMO [PDF]

, 2014
A surface diurnal warm layer is diagnosed from Seaglider observations, and develops on half the days in the CINDY/DYNAMO Indian Ocean experiment. The diurnal warm layer occurs on days of high solar radiation flux (>80 W m-2) and low wind speed (

Eastward Propagation of Anomalous Indo–Pacific Walker Circulation During ENSO Transition

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract By analyzing the zonal mass streamfunction over the equatorial Indo–Pacific region in the period 1979–2024, we found that during the decaying phase of 13 out of 31 El Niño‐Southern Oscillation (ENSO) events, the anomalous Indo–Pacific Walker Circulation (IPWC) propagates steadily eastward across the warm pool. Vertical velocity, precipitation,

A statistical–dynamical approach for probabilistic prediction of sub-seasonal precipitation anomalies over 17 hydroclimatic regions in China [PDF]

, 2023
In this study, we develop a spatial–temporal projection-based calibration, bridging, and merging (STP-CBaM) method to improve probabilistic sub-seasonal precipitation forecast skill over 17 hydroclimatic regions in China.

Maintenance of Moisture Anomalies Across Synoptic and Intraseasonal Timescales Over the Indo‐Pacific Warm Pool

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 9, 16 May 2026.
Abstract Moisture variability plays a fundamental role in regulating tropical precipitation; however, the mechanisms that sustain moisture anomalies across different timescales remain unclear. This study examines how moisture anomalies are regulated over the Indo‐Pacific warm pool using the column‐integrated moist static energy (CMSE) budget.

Carbon isotope fractionation between amorphous calcium carbonate and calcite in earthworm-produced calcium carbonate [PDF]

, 2017
In this study we investigate carbon isotope fractionation during the crystallization of biogenic calcium carbonate. Several species of earthworm including Lumbricus terrestris secrete CaCO3. Initially a milky fluid comprising micro-spherules of amorphous

Distinct Dominant Intraseasonal Oscillation Modes Modulate South China's Persistent Extreme Precipitation in Rainy Season

Geophysical Research Letters, Volume 53, Issue 6, 28 March 2026.
Abstract This study investigates mechanisms by which distinct intraseasonal oscillation modes drive regional persistent extreme precipitation events over South China during the rainy season. Based on periodic characteristics of 54 such events, two dominant modes are identified: 12–20‐day (type‐1) and 25–50‐day (type‐2) oscillations. Although comparable

Eastward-shifting boreal summer intraseasonal oscillation amplifies North America heatwave and wildfire risks in warming climate

npj Climate and Atmospheric Science
Boreal summer intraseasonal oscillation (BSISO) is a key component of tropical climate variability, characterized by eastward and northeastward propagation of organized convection across the Indo-Pacific region.
