Exploration of Predictors for Statistical‐Dynamical Subseasonal Prediction of Western North‐Pacific Tropical Cyclone Activity in Earth System Models

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 6, 28 March 2025.
Abstract Subseasonal prediction of tropical cyclones (TCs) has many potential applications but remains a challenge due to biases in both model‐based large‐scale conditions and TCs in coupled global models. Model forecasts of environmental parameters can be linked to TC activity and then be used to extend the horizon of useful skill through statistical ...

An assessment of Indian monsoon seasonal forecasts and mechanisms underlying monsoon interannual variability in the Met Office GloSea5-GC2 system [PDF]

, 2016
We assess Indian summer monsoon seasonal forecasts in GloSea5-GC2, the Met Office fully coupled subseasonal to seasonal ensemble forecasting system. Using several metrics, GloSea5-GC2 shows similar skill to other state-of-the-art forecast systems.

South American Intraseasonal Oscillation: EOF and Neural Network Approaches

Journal of Geophysical Research: Atmospheres, Volume 130, Issue 5, 16 March 2025.
Abstract This study introduces four univariate regional indices to improve the representation of intraseasonal rainfall variability across South America throughout the year, focusing on Brazil. These indices are constructed using two distinct approaches: the linear Empirical Orthogonal Functions (EOF) method and the unsupervised machine‐learning Self ...

Diurnal Cycle of ASCAT-Identified Cold Pools and Associated Convective Systems in the Maritime Continent and South China Sea [PDF]

Mesoscale convective cold pools are known to alter the turbulent air-sea fluxes in the regions of active convection such as maritime tropics. Satellite-based Ocean Vector Wind instruments have proven to be useful in observing these mesoscale outflows ...

Intraseasonal Variability of Apparent Heat Source over the Arabian Sea and Its Relationship with East Asian Summer Precipitation

Journal of Marine Science and Engineering
Boreal summer intraseasonal oscillation (BSISO) is highly related to summer monsoon activities, tropical cyclones, flood disasters, and other extreme weather events in the Northern Hemisphere. The propagation of BSISO has considerable complexity.

Enhanced Pacific Northwest heat extremes and wildfire risks induced by the boreal summer intraseasonal oscillation

npj Climate and Atmospheric Science
The occurrence of extreme hot and dry summer conditions in the Pacific Northwest region of North America (PNW) has been known to be influenced by climate modes of variability such as the El Niño-Southern Oscillation and other variations in tropospheric ...
