Shallow water waves are seen in oceanography, atmospheric science, and other fields. In this paper, we investigate an extended (3+1)-dimensional shallow water wave equation. We get the travelling-wave solutions via the polynomial-expansion method. Applying the Hirota method and symbolic computation, we derive some mixed-lump-kink and mixed-rogue-wave-kink solutions. Based on the mixed-lump-kink solutions, we graphically show the interaction between a lump and a kink soliton, and find two different cases: (1) the lump merges into the kink soliton; (2) the lump separates from the kink soliton. Based on the mixed-rogue-wave-kink solutions, we graphically analyze the interaction between the rogue wave and two-kink solitons, and find that the rogue wave emerges from the one kink soliton and merges into the other kink soliton.

Recovering additional historical weather observations from known archival sources will improve the understanding of how the climate is changing and enable detailed examination of unusual events within the historical record. The UK National Meteorological Archive recently scanned more than 66,000 paper sheets containing 5.28 million hand‐written monthly rainfall observations taken across the UK and Ireland between 1677 and 1960. Only a small fraction of these observations were previously digitally available for climate scientists to analyse. More than 16,000 volunteer citizen scientists completed the transcription of these sheets of observations during early 2020 using the RainfallRescue.org website, built using the Zooniverse platform. A total of 3.34 million observations from more than 6000 locations have so far been quality controlled and made openly available. This has increased the total number of monthly rainfall observations that are available for this time period and region by a factor of six. The newly rescued observations will enable longer and much improved reconstructions of past variations in rainfall across the British and Irish Isles, including for periods of significant flooding and drought. Specifically, this data should allow the official gridded monthly rainfall reconstructions for the UK to be extended back to 1836, and even earlier for some regions. [ABSTRACT FROM AUTHOR]

This paper analyzes how the atmospheric science of transboundary air pollution was employed as a technopolitical strategy to secure a nation’s volumetric territory. In South Korea, border-crossing particulate matter from China has emerged as a controversial diplomatic concern. The Korean government heavily funded atmospheric science to monitor the transboundary incursion and quantify the amount of Chinese influence. The geoscience of polluted air was mobilized to restore the nation’s aerial sovereignty when transboundary materiality threatened its political authority to regulate atmospheric territory. The paper further examines how nationalistic science was challenged by an international air quality survey called KORUS-AQ, a study co-organized by NASA and Korea’s National Institute for Environmental Research. Korean experts used the joint mission with NASA to verify the transboundary impact on Seoul’s air quality and hold China responsible. US scientists, however, challenged this nation-centered vision by highlighting the underestimated domestic sources of air pollution. As a result, the aerial survey did not generate a unilateral understanding of nature but produced multiple and even contrasting territorial imaginations on a single airshed. Atmospheric science, I argue, functioned as a geopolitical arena where different visions on volumetric governance were enacted and competed. [ABSTRACT FROM AUTHOR]
