Summary: This letter proposes a new wind speed inversion algorithm based on HF radar-estimated wind-driven sea surface current, utilizing an artificial neural network to establish an accurate model between wind-driven current speed and wind speed. The field experiment demonstrates an average correlation coefficient of 0.86 and an average root mean square error of 2.38 m/s between radar-estimated wind speed and reference wind speed, with larger measurement range and better spatial resolution compared to traditional algorithms.

Summary: The Chukchi Slope Current is a westward-flowing current along the Chukchi slope, which has a significant impact on the hydrographic structure and ecosystem of the region. This study uses numerical modeling to investigate the energetics of the slope current during the ice-covered period. The results show that ice friction plays a crucial role in suppressing the growth of surface eddies and driving Ekman pumping to decrease the available potential energy and kinetic energy of the mean flow and mesoscale eddies.

Summary: The Mediterranean Sea is a climate-change hot spot, and high-frequency radars (HFRs) have proven to be effective in monitoring surface circulation, waves, and winds in coastal areas. The use of HFRs has enhanced our scientific knowledge of coastal processes and has various applications in maritime safety, extreme hazards, and environmental transport.

Summary: The effective carriers of Sargassum in the Caribbean Sea are identified as mesoscale eddies with coherent boundaries, which can harbor finite-time attractors for networks of buoyant or inertial particles. The mechanism of coastal choking is attributed to thermal instability in the presence of bottom topography, as identified in a minimal model of surface-intensified Caribbean Sea eddies.

Summary: The study investigated the accuracy of SeaSonde High Frequency (HF) radar wind direction measurements in the Gulf of Naples, showing that the data is reliable when wind speeds exceed 5 m/s. Despite limitations, the study confirmed the potential of these systems as monitoring platforms in coastal areas and suggested further efforts towards improvement.

Summary: The study of intraseasonal variability in the Kuroshio east of Taiwan reveals complex dynamics influenced by various factors such as ocean eddies, surface eddies, and coastal cold water upwelling. Ocean eddies southeast of Taiwan have a significant impact on the intraseasonal variability in the Kuroshio.

Summary: The region where the East Australian Current separates from the coast is influenced by mesoscale circulation, with different circulation modes leading to varying upwelling, retention, or export. The sources and pathways of water transport are also affected by the mesoscale circulation. The highest proportion of upwelling occurs upstream of 32.5 degrees S, while the highest retention occurs immediately downstream of the EAC separation region.

Summary: The boundary current system in the Labrador Sea plays a crucial role in regulating convection in the interior basin. Research has revealed persistent mesoscale variability in the West Greenland boundary current and identified intensified cyclones as the downstream manifestation of Denmark Strait Overflow Water (DSOW). Quantifying these cyclones has shown that they transport dense water and increase the transport of DSOW in the West Greenland boundary current.

Summary: The transfer of momentum between the atmosphere and ocean depends on the velocity difference between seawater and air, neglecting relative wind may lead to increased Eddy Kinetic Energy. Neglecting relative wind can also affect heat transport, influencing the seasonal ice zone.

Summary: The study introduces a method to retrieve significant wave heights from coastal areas affected by nononshore winds, utilizing an artificial neural network algorithm to improve estimations from radar images. By including the square root of the signal-to-noise ratio, nearshore radar subimage power, and in situ wind components in the input layer, more reliable estimations for both onshore and nononshore wind cases are achieved.

Summary: This study presents the application of adaptive clutter suppression technique to mitigate aerial clutter in a wind profiler radar. By computing the weighted sum of signals collected from different antenna subarrays, the power of the output signals is minimized to effectively solve the issue of overlap between aerial clutter and desired echoes.

Summary: This article presents an indirect wind field nowcasting scheme based on lidar observation. The proposed network, consisting of an encoder-forecaster network and a mask branch, is trained and evaluated using lidar observations at Hong Kong International Airport in 2020. Comprehensive comparison with other methods demonstrates the good performance of the network in capturing spatio-temporal features and achieving fine-scale wind field nowcasting results with high efficiency.

Summary: This paper investigates wind energy resources and thermal characteristics in a coastal region of Hong Kong using a Doppler wind sodar and a microwave radiometer. It analyzes wind climatology and variability, evaluates statistical distributions of wind speed, examines the probability distribution and variation of atmospheric stability, and investigates the spatiotemporal variation of wind power density. The results provide insights and references for coastal wind farm development.
