Short summary
The city significantly influences thunderstorm and lightning activity, yet the potential mechanisms remain largely unexplored. Our study has revealed that both city size and building density play pivotal roles in modulating thunderstorm and lightning activity. This research not only deepens our understanding of urban meteorology but also lays an important foundation for developing accurate and targeted urban thunderstorm risk prediction models.

This paper introduces a new chemistry-climate model MACO and evaluates its performance through a historical simulation. MACO demonstrates robust capabilities in simulating key middle atmospheric dynamical and chemical processes. Despite some identified biases in the upper stratosphere and mesosphere that require future model improvements, our results suggest that MACO is a suitable tool for middle atmosphere research involving chemistry-climate interactions.

Current observations at two moorings in the northern South China Sea reveal that mesoscale eddies can transfer energy with near-inertial oscillations (NIOs). Numerical experiments are conducted to investigate important parameters affecting energy transfer between mesoscale eddies and NIOs, which demonstrate that the energy transferred by mesoscale eddies is larger with stronger winds and higher strength of the mesoscale eddy. Anticyclonic eddies can transfer more energy than cyclonic eddies.

We developed a modelling system of the northwest Atlantic Ocean that simulates the currents, temperature, salinity, and parts of the biochemical cycle of the ocean, as well as sea ice. The system combines advanced, open-source models and can be used to study, for example, the ocean capture of atmospheric carbon dioxide, which is a key process in the global climate. The system produces realistic results, and we use it to investigate the roles of tides and sea ice in the northwest Atlantic Ocean.

We focus on the interactions among TLEs, lightning, and the ionospheric electric field. The SNR of the Schumann resonance at the first and second modes dropped during the TLEs. A significant enhancement of the energy in ULF occurred. Distinct lightning whistler waves were found in the VLF band. Our results indicate that the observations of electric fields from the satellite could possibly be utilized to monitor lower-atmospheric lightning and its impact on the space environment.

Microphysical characteristics of convective overshooting are essential but poorly understood, and we examine them by using the latest data. (1) Convective overshooting events mainly occur over NC (Northeast China) and northern MEC (Middle and East China). (2) Radar reflectivity of convective overshooting over NC accounts for a higher proportion below the zero level, while the opposite is the case for MEC and SC (South China). (3) Droplets of convective overshooting are large but sparse.

A compact all-fiber coherent Doppler wind lidar (CDWL) working at the 1.5 µm wavelength is applied to probe the dynamics and microphysics structure of thunderstorms. It was found that thunderclouds below the 0 ℃ isotherm have significant spectrum broadening and an increase in skewness, and that lightning affects the microphysics structure of the thundercloud. It is proven that the precise spectrum of CDWL is a promising indicator for studying the charge structure of thunderstorms.

Our results suggest that lightning strokes would probably influence the ionosphere and thus give rise to the occurrence of a sporadic sodium layer (NaS), with the overturning of the electric field playing an important role. Model simulation results show that the calculated first-order rate coefficient could explain the efficient recombination of Na+→Na in this NaS case study. A conjunction between the lower and upper atmospheres could be established by these inter-connected phenomena.

Short summary
We investigated how boreal winter sea surface temperatures anomaly in the central tropical Pacific impact the Antarctic stratosphere months later. Using 45 years of reanalysis data, we found that warmer sea surface lead to a warmer Antarctic stratosphere during the subsequent austral winter. This link, driven by the planetary waves and reinforced by regional sea-ice loss, provides a new insight to make long-range forecasts for stratospheric warming.
