Toward Improved Tropical Cyclone Forecasting: An Optimized Strategy Combining Dynamic Initialization and Bogus Data Assimilation

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 12, 28 June 2026.
Abstract In numerical weather prediction, dynamic initialization (DI) of tropical cyclones (TCs) and bogus data assimilation (BDA) are two widely used vortex initialization methods, both of which substantially affect the track and intensity of simulated TCs.

Global Hotspots of Stalling Extratropical Cyclones

open access: yesGeophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Extratropical cyclones (ETCs) are primary drivers of extreme weather in the mid‐to‐high latitudes. We introduce a new classification of particularly impactful events—“stalling” ETCs—defined by slow movement combined with intense precipitation. Using cyclone tracking data, we find that stalling ETCs cluster systematically along the east coasts ...

Historical Increase in Autumn and Winter Cyclone‐Associated Precipitation Over the Arctic Ocean Driven Primarily by Enhanced Arctic Evaporation

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 11, 16 June 2026.
Abstract What is the relative importance of variability in local evaporation versus moisture convergence from lower latitudes to changes in autumn/winter Arctic Ocean precipitation? Past research has offered sometimes contradictory answers. Here we offer some resolution to this question by addressing two research gaps.

Buoyancy Flux and Its Environmental Modulation in the Vertical Development of Shallow Cumulus in the Central Amazon

open access: yesJournal of Geophysical Research: Atmospheres, Volume 131, Issue 11, 16 June 2026.
Abstract This study investigates the vertical development of shallow cumulus (ShCu) clouds in the Central Amazon (CAMZ) by combining large‐eddy simulations (LES) with observational data from the GoAmazon2014/5 campaign. Analyses of turbulent kinetic energy budgets, updraft mass flux, moisture flux, and surface fluxes across cloud sizes indicate that ...

Understanding the Formation and Intensification Process of Several Cyclonic Systems over the Bay of Bengal using the Revised Genesis Potential Parameter Index

open access: yes
The Bay of Bengal experiences numerous low-pressure systems almost throughout the year. However, only a small fraction of these systems intensify into catastrophic storms.
