Special Issue Information

Dear Colleagues,

The ocean dynamics in tropical cyclones (TC) is an interesting topic in oceanography. With the development of remote sensing oceanic dynamics (i.e., wind and wave), targets and oil spills are detectable by SARs, i.e., Sentinel-1, COSMO-SkyMed, etc. Compared with scatterometer and altimeter, SAR with fine spatial resolution and wide swath coverage has great ability in a TC, which can simultaneously measure upper dynamics. In addition, numeric models are usually employed in TC-relevant research, i.e., huge waves, SST cooling, etc. This Special Issue will present the TC relevant researches, i.e., wind profile, air–sea interaction, extreme waves, current, rain, etc., utilizing SAR measurements and numeric models. Moreover, it is worthwhile to research the characteristics of TC using remote-sensed products.

SAR is an advanced sensor for upper ocean monitoring. During the Satellite Hurricane Observation Campaign (SHOC), tropical cyclones are captured by various SARs, i.e., Sentinel-1 and Gaofen-3. In this sense, developing algorithms for SAR retrievals in tropical cyclones is worthwhile. Furthermore, combining the SAR measurements and numeric models brings the opportunity to prompt research on the complicate dynamics at air–sea layer.

This Special Issue welcomes the submission of original research manuscripts or reviews in, but not limited to, the following topics:

  • Backscattering theory of remote sensing in tropical cyclone;
  • Algorithm for SAR retrievals (i.e., wind, wave, current, etc.);
  • Extreme sea state using a numeric wave model;
  • Disaster assessment caused by tropical cyclone;
  • Analysis of characteristics of tropical cyclone;
  • Other tropical cyclone-relevant applications using other remote sensors.

In a SAR image acquired by the ERS-2 satellite, crossed “X-shape” internal solitary waves (ISWs) south to Dongsha Island are found to be a wave–wave interaction composed of five solitons: two head waves, two tail waves, and the overlapped part. To explain this remote sensing phenomenon, based on a high-resolution three-dimensional MIT general circulation model (MITgcm) using realistic topography and tidal forcing, the “X-shape” internal waves are reproduced at the same location. The development processes of the waves indicate that the “X-shape” ISWs are two waves diffracted from one internal wave southeast to Dongsha Island. During the propagation, the amplitude of their overlapped part of the “X-shape” ISWs becomes significantly larger than the sum of the amplitudes of both head waves, which proves that nonlinear wave–wave interaction has occurred. Based on wave–wave interaction theory, the theoretical maximum value of the amplitude of the overlapped part at the initial moment is calculated as 14.12 m, which is in good agreement with the model results of 14 m. Meanwhile, the variation of the theoretical amplitude of the overlapped part is basically consistent with that of the modeled one, confirming the occurrence of the wave–wave interaction. Besides, when the waves propagate over varying water depths, the type of the wave–wave interaction can change rather than being fixed from the start. Full article
