The Arctic climate system involves dynamic interactions between the atmosphere, sea ice, and ocean. However, due to the lack of comprehensive observations and analyses in previous studies, these interactions are not fully understood. Watkins et al. [2024] collected a large set of observational data from stations, weather balloons, radars, buoys and performed an in-depth analysis of how Arctic sea ice and ocean responded to a strong cyclone passing over the Arctic during the winter of 2019-2020.

AbstractGeologic evidence and palaeoclimate simulations have indicated the existence of an extensive, interconnected megamonsoon system over the Pangaea supercontinent. However, the ways in which subsequent continental break-up about 180 million years ago and reassembly in the Cenozoic, as well as large global climatic fluctuations, influenced the transition to the modern global monsoon system are uncertain.

The dryline is a narrow zone of extremely sharp moisture gradient. It is also usually called the “moisture front”, resembling the cold and warm fronts of thermal contrasts. Drylines occur in many regions of the world in late spring and summer seasons, such as the Great Plains of the United States, India, and northern China (Schaefer, 1986, p. 549-572). Usually, drylines are associated with convective developments or even severe thunderstorms, such as tornados and squall lines. van Schalkwyk et al.
