Microcylinder and Slot Combination for Flow Separation Control Over a Wind Turbine Airfoil

Wind Energy, Volume 28, Issue 7, July 2025.
ABSTRACT This study explores a novel passive flow control strategy combining a microcylinder and slot configuration to mitigate flow separation over an S809 wind turbine airfoil under stall conditions at a Reynolds number of 106. Numerical simulations are conducted using the Reynolds‐averaged Navier–Stokes (RANS) approach. The primary objectives are to

MF‐UFNO: A Fourier Neural Operators‐Based Model for Radar Echo Extrapolation

Earth and Space Science, Volume 12, Issue 7, July 2025.
Abstract Severe convective weather events, such as heavy rainfall and flooding, are serious threats to human society. However, accurate nowcasting of these events using radar remains challenging due to the complex dynamics and nonlinear physical processes involved.

A Flash Flood Numerical Modeling and Forecasting Tool in Mountainous Small Catchments Based on a 2‐D Hydrodynamic Model

Earth and Space Science, Volume 12, Issue 7, July 2025.
Abstract The forecasting and early warning of flash floods in mountainous areas are extremely challenging. Here, we establish an integrated model of Baseflow‐Rainfall‐Interception‐Flood (BRIF) to support efficient numerical modeling and potential forecasting of flash flood in future.

Impact of Data Assimilation Frequency and Observation Location in Thermal Effluent Modeling for Coastal Waters

Earth and Space Science, Volume 12, Issue 7, July 2025.
Abstract This study investigates the application of data assimilation (DA) using the Ensemble Kalman Filter (EnKF) to address the uncertainties associated with modeling the thermal effluents discharged from power and desalination plants into a shallow, tidal bay.

Comparisons Between the Global Ionosphere Thermosphere Model and HIWIND Measurements

Journal of Geophysical Research: Space Physics, Volume 130, Issue 7, July 2025.
Abstract Neutral winds in the daytime middle thermosphere are difficult to measure. The High altitude Interferometer WIND Observation instrument made measurements of these winds from a balloon in the summers of 2011 and 2018 during both daytime and nighttime at high latitudes.
