Summary: A new study reveals that the occurrence of summer heatwaves in India is influenced by the large scale atmospheric circulation associated with the Pacific Meridional Mode. The study identifies a significant link between the positive phase of the PMM and increased intensity and duration of heatwaves in North Central India. The findings also suggest that future heatwaves could become even more intense due to anthropogenic warming, which has important implications for mitigation and adaptation strategies.

Summary: The study found that emissions of non-methane hydrocarbons (NMHC) and PM2.5 decreased by over 40% from 2003 to 2015 in Hong Kong. However, motorcycles and LPG-fueled public light buses emitted disproportionately high levels of carbon monoxide (CO) and NMHC, indicating the need for additional emission controls. Additionally, fuel economy improvements did not lead to expected reductions in carbon dioxide (CO2) emissions, underscoring the need for more aggressive CO2 reductions, especially from heavy-duty vehicles.

Summary: During El Nino developing summers, BSISO-related convections are stronger and more organized with northward propagation compared to decaying summers. The easterly vertical shear in the developing phase remarkably increases due to enhanced upper-level easterly anomaly, leading to stronger air-sea interaction and amplifying northward propagation.

Summary: The El Nino-Southern Oscillation (ENSO) is a consequential climate phenomenon affecting global extreme weather events often with largescale socioeconomic impacts. Research has found that the economic damage from El Nino is far greater than the benefits from La Nina, and under greenhouse warming, increased ENSO variability leads to increased economic loss.

Summary: By analyzing observational data and conducting model experiments, this study finds that the heatwave intensity in China experienced a significant increase during the transition period of 1993-2000, and this intensification remains robust in northern and western regions even after removing the warming trend. The combined impacts of ENSO, AMO, and IOD explain a substantial portion of the observed heatwave intensification in specific regions. The results emphasize the importance of concurrent phase transitions of decadal climate modes in regulating heatwaves.

Summary: The study found that former and current use of HTPs was associated with persistent respiratory symptoms among youth, especially among those who never or formerly smoked cigarettes. Respiratory symptoms were more prevalent in ever exclusive HTP users and ever dual users compared to ever exclusive cigarette users. These findings suggest that using HTPs instead of cigarettes may not reduce health risks.

Summary: The Madden-Julian Oscillation (MJO) response to sea surface temperature anomalies in equatorial Pacific impacts westerly wind bursts (WWBs) differently during El Nino onset and development. During El Nino onset, MJO shifts toward the equator, while in development stage, MJO strengthens in central Pacific. These changes enhance MJO activity along the equator, facilitating WWBs.

Summary: The intensity and persistence of Northeast Pacific marine heatwaves (MHWs) are influenced by both local atmospheric forcing and large-scale climate influences. Sea surface temperature and sea surface height anomalies play crucial roles in the development of MHWs, with subsurface ocean dynamics being relevant. The growth of Northeast Pacific MHWs is part of a basin-scale dynamical mode that connects the North Pacific with central equatorial Pacific El Nino events, potentially prolonging the duration of MHWs.

Summary: The North Pacific Oscillation (NPO) plays a role in triggering El Nino-Southern Oscillation (ENSO) through the seasonal footprinting mechanism (SFM). The efficiency of SFM varies among models and depends on the background mean state of the model. Greater intensification of the northern branch of the Pacific intertropical convergence zone (ITCZ) leads to stronger SFM efficiency and better triggers ENSO events.

Summary: Building photovoltaic (PV) in big cities is a growing trend, but the lack of measured radiation data on vertical surface is a challenge. This study reviews ten solar radiation models to find the optimal one for calculating solar radiation on vertical surface in high turbidity areas like Beijing. The accuracy of the models is also examined in relation to atmospheric turbidity. The results suggest that the Perez model is suitable for calculating solar radiation, but high atmosphere turbidity may affect its accuracy. The study provides guidance for the deployment of building PV systems in Beijing, with an estimated annual AC output energy of 630-971 kWh/kWp.

Summary: This study investigates the influence of urbanization on mesoscale convective systems (MCS) in the Yangtze River Delta region in China under different synoptic conditions using various observations. The results show that the strength of synoptic forcing can help distinguish the effects of land cover and land use on MCS. When synoptic-scale forcing is weak, the urban heat island (UHI) is the main factor affecting cloud development. On the other hand, when strong synoptic-scale forcing is present, buildings in cities cause clouds to bifurcate upwind of cities. The combined analysis of observations and model simulations provides new insights into the net effects of urbanization on cloud systems.

Summary: This study investigates the tropospheric gravity waves in China using high-resolution radiosonde data set. The results show that the total energy of tropospheric gravity waves exhibits significant seasonal variations at low and middle latitudes, with the highest energy in winter and the lowest in summer. The upper tropospheric jet stream is the main source of gravity waves in low and middle latitudes, leading to southward propagation of maximum energy in the cold season. During the summer in southern China, convective precipitation contributes to the enhancement of gravity wave energy. Furthermore, the strength of the low-level wind over the Tibetan Plateau accounts for 12.4% of the observed gravity wave energy.

Summary: The Sichuan Basin is one of the most air-polluted areas in China, and this study investigates the formation and evolution of multilayer inversions during persistent heavy pollution events in the region. The results show that over 90% of the events included multilayer inversions, occurring near the ground and at heights of approximately 2000-3800 m above the ground. These inversions were influenced by large-scale pressure patterns and mid-level warm air advection induced by warm high-pressure ridges. Cold advection associated with cold low-pressure troughs played a role in weakening and ending the inversions.

Summary: This study derives horizontal divergence (and vertical motion) profiles from horizontal wind measurements obtained from two radar wind-profiler (RWP) mesonets in East China, and examines their relationship with convection initiation (CI) occurring within one mesonet and an intense squall line moving across another mesonet. The results show that the RWP mesonets, along with automated surface observations, can realistically provide lower-tropospheric profiles of horizontal divergence (and upward motion) associated with CI and the evolution of the squall line. High-resolution surface observations resolve better divergence induced by localized CI, while the RWP measurements capture significant convergence before the onset of squall precipitation. Statistical analysis indicates that lower-tropospheric convergence can be detected up to about 40 minutes in advance of heavy rainfall, with higher correlation closer to the heavy rainfall time. Approximately 40% of heavy rainfall moments are accompanied by strong convergence signals occurring mostly near the top of the boundary layer. This work suggests that integrating RWP and surface wind measurements can aid in nowcasting the location and timing of CI and the development of convective storms.

Summary: This study evaluates the errors and representativeness of the Atmospheric Infrared Sounder (AIRS) version 6 (v6) and version 7 (v7) temperature profiles in the Arctic region. The results show that v7 has smaller biases in the troposphere compared to v6, but the profile-averaged root mean square error (RMSE) increased in v7, particularly in winter. The accuracy of AIRS temperature retrieval is primarily influenced by surface type and cloud fraction.

Summary: Accurate estimation of wind speed at wind turbine hub height is important for wind energy assessment and exploitation. The traditional power law method (PLM) can lead to uncertainties, especially under unstable conditions. In this study, a random forest (RF) machine learning algorithm is used to estimate wind speeds at hub heights beyond the traditional limit of 100-120 m. The RF model shows advantages over the PLM model, considering factors such as surface friction and heat transfer. The findings have implications for the wind energy industry.

Open-access gridded precipitation products (OGPPs) are important sources due to their continuous spatiotemporal coverage. This study proposes a methodology to comprehensively compare the accuracies and stabilities of ten different OGPPs, particularly in mountainous basins. The results show high accuracy but unstable performance of all OGPPs, with multi-source fusion-type products offering better stability and accuracy. Multi-source weighted-ensemble precipitation and climate prediction center morphing method products exhibit the best comprehensive performance.

Summary: This study, based on reanalysis data from 1980 to 2019, reveals that the relationship between autumn sea ice concentration in the Barents-Kara Seas (BKSIC) and subsequent winter North Atlantic Oscillation (NAO) underwent an interdecadal weakening in the early 1990s. The weakening can be attributed to the decrease in the interannual variability of BKSIC, which leads to a discrepancy in the tropospheric warming. In the former period (1980-1993), the decrease in autumn BKSIC enhances tropospheric warming and weakens the circumpolar westerly, resulting in a negative NAO phase. However, in the latter period (1994-2019), the smaller interannual variability of BKSIC weakens its influence on the tropospheric temperature, diluting the relationship with the subsequent winter NAO.
