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

Journal 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.

Radiosonde measurements during POLARSTERN cruise PS110 (ANT-XXXIII/1)

, 2019
The launch site is located 10m above sea level. The first row of each sounding holds surface data for TTT, RH, ff and dd, which is not acquired by the radiosonde. The measuring height of TTT and RH is 29m, and 39m for dd and ff.

GNSS Zenith Wet Delay as a Boundary Layer Diagnostic: Regime‐Dependent Turbulence Signatures From Large Eddy Simulation and Observations

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 12, 28 June 2026.
Abstract Global Navigation Satellite Systems (GNSS) provide continuous measurements of zenith wet delay (ZWD), reflecting column‐integrated atmospheric water vapor. While the slowly varying ZWD is routinely assimilated in numerical weather prediction, the rapid fluctuations on timescales of seconds to minutes that arise from boundary‐layer turbulence ...

Mesoscale Soil Moisture Heterogeneity Can Locally Amplify Humid Heat

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Soil moisture is a key ingredient of humid heat through supplying moisture and modifying boundary layer properties. Soil moisture heterogeneity due to for example, antecedent rainfall, can strongly influence weather patterns; yet, its effect on humid heat is poorly understood.

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

Journal 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 ...

Radiosonde measurements during POLARSTERN cruises (ANT-I/1 - PS109)

Since Polarstern's maiden cruise ANT-I/1 the meteorological observatory Polarstern continuously performs radiosoundings during times of ship operation. Typically, there is one launch to full altitude at 12 UTC every day.

Reconstructing Marine Boundary Layer Jets Over the South China Sea Using Machine Learning

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Marine boundary layer jets (MBLJs) over the South China Sea (SCS) play a critical role in coastal heavy rainfall, yet their structure remains uncertain due to limited wind observations over the ocean. Here, we develop a U‐Net–based reconstruction framework to estimate 950‐hPa winds from satellite‐derived sea surface winds, providing a ...

Ensemble‐Based Assimilation of Sounding Observations With AI Weather Models

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract The artificial intelligence (AI)‐based weather models have shown great promise for weather forecasts. But they rely on the initial conditions provided by traditional paradigm of numerical weather prediction, which has a cycled data assimilation (DA) to combine short‐term forecasts and observations.

Real-Time GNSS-Derived PWV for Typhoon Characterizations: A Case Study for Super Typhoon Mangkhut in Hong Kong

Remote Sensing, 2019
Typhoons can be serious natural disasters for the sustainability and development of society. The development of a typhoon usually involves a pre-existing weather disturbance, warm tropical oceans, and a large amount of moisture. This implies that a large
