Summary: Several simulation studies have shown that sea-breeze fronts (SBFs) can penetrate far inland through the Beijing-Tianjin-Hebei urban agglomeration (BTH) from the Bohai Bay coast. However, there is limited observational evidence to support this claim. Through dense surface observation networks, we observed a SBF that penetrated 170 km inland from Bohai Bay and interacted with cities in the BTH. The SBF was slower in urban areas, causing a bending of the front line, and resulted in a temporary increase in surface air temperature in both urban and rural areas.

Summary: In this study, the numerical simulation of sea breeze (SB) and its associated convective initiation (CI) in the Florida peninsula was conducted using the WRF model. The results show that the WRF model can accurately reproduce the observed SB CI, and the resolution and accurate representation of geophysical variables play a significant role in improving the simulations.

Summary: Convection on tropical islands, such as Hainan Island, is influenced by local circulations responding to lower-troposphere ambient flow and diurnal thermal heating. In high-wind conditions, convection initiates predominantly over lee-side plains, while in low-wind conditions it initiates over mountains.

Summary: The applicability of the planetary boundary layer (PBL) scheme in the WRF model varies in different regions. The choice of the WRF PBL scheme is crucial when simulating a sea-land breeze (SLB) process. The study found that only the YSU and SH schemes are suitable for simulating SLB in Shanghai, as they provide accurate results and can simulate the coupled structure of sea-land circulation and heat island circulation.

Summary: Heatwaves have implications for human health and ecosystem function, particularly in urban areas where temperatures may be higher due to the urban heat island effect. In coastal cities like Sydney, sea breezes can provide relief, but topographic features and urban heat can offset this cooling influence. Convection-permitting simulations show that the interaction between sea breezes and urban heat can significantly impact temperature gradients and heat dispersion in the city.

Summary: Observations were collected along a sea-coast-inland area, showing that the planetary boundary layer heights varied across different locations and seasons. The sea breeze had little seasonal difference in the daily variation of sensible heat flux, and the duration and extension of sea breeze differed between summer and winter. PM2.5 concentrations also varied between coastal and inland areas, with different vertical profiles in winter and summer. The analysis of a land-sea breeze episode revealed the impact on wind and temperature profiles, resulting in a high concentration center of PM2.5 at a certain height. These findings provide insights into the structure of the land-sea planetary boundary layer and support the prediction of heavy pollution episodes.

Summary: The Long Island Sound Tropospheric Ozone Study aimed to improve the understanding of ozone chemistry and transport from New York City to the Long Island Sound and Connecticut coastline. The study found that using higher model resolutions can enhance the simulation of sea breeze circulations, low-level jets, and boundary layer evolution, resulting in improved surface meteorology statistics and more accurate ozone predictions.

Summary: A study evaluated the wind field simulated by ten different planetary boundary layer parameterization schemes using a three-dimensional Doppler Wind Lidar. The results showed that the characteristics of the simulated wind field are highly sensitive to the boundary layer parameterization schemes, especially for the sea-land breeze. GBM, MYNN2, and YSU schemes produced more realistic results for the wind field and the occurrence of sea-land breeze due to their inclusion of entrainment effects and local gradient correction terms.

Summary: The relative contributions of local and remote wind stress and air-sea buoyancy forcing to sea-level variations along the East Coast of the United States are investigated. Wind stress explains a significant portion of the interannual sea-level variance, while both wind and buoyancy forcing together explain a larger portion. The study also disproves a previous hypothesis about the Labrador Sea wind stress being a driver of Nantucket sea-level variations. Remote buoyancy forcing is found to influence Nantucket sea level through slow advective processes.

Summary: The study finds that the Madden-Julian Oscillation (MJO) has a significant impact on the precipitation anomaly over Borneo. Linear theory analysis reveals that the prevailing wind and topography are the key factors controlling the asymmetry and dipolar pattern of the precipitation anomaly. Nonlinear simulations further demonstrate the effects of island topography and solar radiative heating in different MJO phases. These findings highlight the distinct roles of MJO wind anomaly, island topography, and solar insolation in the formation of the dipolar pattern of Borneo precipitation.

Summary: This study examines the severe air pollution in the Arve river valley, attributing it mostly to local emission sources with the central basin-shaped section being the most affected. While other valley sections show a more complex distribution of pollution, with contributions from both local and non-local sources being significant.

Summary: The study investigates the impact of synoptic weather and larger scale circulation patterns on regional weather and extreme events over Asia. Model results suggest future changes in circulation patterns and increase in wintertime minimum temperatures by 3-4 degrees C by 2050. Anti-cyclonic activity may play a key role in influencing heat waves and droughts in various regions of Asia.

Summary: This study, coordinated by the WMO/GAW programme, aims to understand the behavior of key air pollutants during the COVID-19 pandemic period. The analysis focuses on changes in air quality in cities across the globe, with decreases observed in NO2 and NOx concentrations correlating with reduced mobility. However, complex signals suggest that sources other than vehicular emissions significantly contributed to the changes in air quality.

Summary: In this study, a WRF-Chem VBS parameterization method is proposed to investigate the uncertainty of organic aerosol production. The results showed structural errors in the model, but it was still possible to identify suitable parameter combinations for the analyzed periods using emulator analysis and model evaluation metrics. This method can be used to determine the model uncertainty and provide valuable information to improve our understanding of OA production.

Summary: The study shows that in Delhi, ozone production is limited by VOC and is particularly sensitive to solar radiation in winter. Reduction in NOx alone increases ozone, while reducing VOC emissions can efficiently decrease ozone. Additionally, reducing PM emissions also increases ozone, especially in winter.
