Special Issue Information

Dear Colleagues,

Meteorological hazards, including extreme precipitation, tornados, hailstorms, lightning, and tropical storms, cause significant damage worldwide. Due to the changing climate and increasing socio-demographic pressures, the risk of these events will only increase over the coming century. Radar observations of these meteorological phenomena have advanced significantly over the last few decades due to the introduction of both Doppler and dual-polarization radar technologies and the increasing prevalence of ground-based, airborne, and spaceborne radars. These advancements have broadened the insight available to meteorologists from radar observations both in a research and operational capacity. Large-scale field campaigns have enhanced our fundamental understanding of atmospheric physics through the synergistic deployment of radars with in situ and airborne sensors, while the expansion of operational weather radar networks has provided the foundation for increasingly sophisticated approaches to inform the real-time management of meteorological hazards based on our improved understanding.

In this Special Issue, we invite contributions which share recent advances in the application of weather radars to both the understanding and operational management of meteorological hazards, including, but not limited to, the following:

  • Multi-radar studies of meteorological events.
  • Synergistic use of radar and complementary sensors.
  • Microphysical insights from radar into meteorological systems.
  • Advances in the use of weather radar in operational meteorological warning and forecasting systems.
  • Radar-based nowcasting of meteorological events.
  • Radar verification of advances to numerical weather prediction.

The accuracy of ERA5 reanalysis datasets and their applicability in the coastal area of Bohai Bay are crucial for weather forecasting and environmental protection research. However, synthesis evaluation of ERA5 in this region remains lacking. In this study, using a tropospheric wind profile radar (CFL-06L) placed in coastal Huanghua city, the deviations of ERA5 reanalysis data are assessed from the ground to an altitude of 5 km. The results indicate that the wind speed of ERA5 reanalysis data exhibits good consistency from the surface to the tropospheric level of about 5 km, with R2 values ranging from 0.5 to 0.85. The lowest mean wind speed error, less than 3 m/s, occurs in the middle layer, while larger errors are observed at the surface and upper layers. Specifically, at 150 m, the R2 is as low as 0.5, with numerous outliers around 5000 m. Seasonal analysis shows that the ERA5 wind field performs best in summer and worst in autumn and winter, especially at lower levels affected by circulation systems, high stratus clouds, and aerosols, with errors reaching up to 10 m/s. Further analysis of extreme weather events, such as heavy rain; hot, dry winds; and snowstorms, reveals that the effects of sea-land winds and strong convective systems significantly impact the observation of wind profiles and the assimilation of reanalysis data, particularly under the constrain of boundary layer height. Additionally, we also find that the transition of sea-land breeze is capable of triggering the nighttime low-level jet, thereby downward transporting the aloft ozone to the ground and resulting in an abnormal increase in the surface ozone concentration. The study provides a scientific basis for improving meteorological forecasting, optimizing wind energy resource utilization, and formulating environmental protection policies, highlighting its significant scientific and practical application value.
