Special Issue Information

Dear Colleagues,

Atlantic tropical cyclones have wreaked havoc on coastal and inland communities, with Hurricanes Harvey, Irma, Maria, Florence and Laura being typical and recent examples. The 2020 hurricane season may be one of the most active Atlantic tropical cyclone seasons in recent decades. This Special Issue will focus on understanding, simulation, and attribution of extreme events in terms of the frequency, landfall, intensity, translational speed, and rainfall of Atlantic tropical cyclones by combining observations, numerical models, and big data/machine learning technologies. Therefore, topics of interest for publication include, but are not limited to:

  • Atmospheric and oceanic drivers of the extremely active hurricane season in terms of frequency or accumulated cyclone energy (e.g., the 2020 season);
  • Attributing and forecasting extreme tropical cyclone rainfall and flooding with observations and numerical models;
  • Understanding the extremely low translational speed of Atlantic tropical cyclones (e.g., Harvey and Florence);
  • Examining extreme teleconnections (Rossby waves) and extratropical transitions associated with Atlantic tropical cyclones;
  • Extreme intensity and intensification rate of Atlantic tropical cyclones;
  • Forecasting and estimating the intensity and rainfall of extremely strong Atlantic tropical cyclones using big data/machine learning technology;
  • Extreme storm surge events and coastal flooding caused by Atlantic tropical cyclones.

Abstract
The Quasi-Biennal Oscillation (QBO) and the El Niño-Southern Oscillation (ENSO) largely modulate the zonal wind in the tropics. Previous studies showed that QBO phases produce changes in deep convection through an increase/decrease in the tropopause height over the tropics and subtropics. This study [...] Read more.
The Quasi-Biennal Oscillation (QBO) and the El Niño-Southern Oscillation (ENSO) largely modulate the zonal wind in the tropics. Previous studies showed that QBO phases produce changes in deep convection through an increase/decrease in the tropopause height over the tropics and subtropics. This study investigates the combined effects of QBO and ENSO on tropical cyclone activity by modulating tropopause height. We found that tropopause height increases over the Gulf of Mexico, the Caribbean region, and the Western North Atlantic Ocean during La Niña + QBOW, allowing deeper tropical convection to develop over those regions. As a consequence, TC activity over those regions is not only increased in number but also enhanced in intensity. Conversely, during El Niño + QBOE, most deep tropical convection is inhibited over those same regions due to the decrease in tropopause height over the subtropics. We conclude that QBO effects on TCs and deep convection should be studied in combination with ENSO. Additional comparative studies using long record data at high vertical resolution are needed to fully understand to what extent QBO interacts with ENSO in the lower tropical stratosphere and upper tropical troposphere.

Changes in the translational speed of tropical cyclones (e.g., sluggish tropical cyclones) are associated with extreme precipitation and flash flooding. However, it is still unclear regarding the spatial and temporal variability of extreme tropical cyclone translation events in the North Atlantic and underlying large-scale drivers. This work finds that the frequencies of extreme fast- and slow-translation events of Atlantic tropical cyclones exhibited a significant rising trend during 1980–2019. The extreme fast-translation events of Atlantic tropical cyclones are primarily located in the northern part of the North Atlantic, while the extreme slow-translation events are located more equatorward. There is a significant rising trend in the frequency of extreme slow-translation events over ocean with no trend over land. However, there is a significant rising trend in the frequency of extreme fast-translation events over ocean and over land. The extreme slow-translation events are associated with a strong high-pressure system in the continental United States (U.S.). By contrast, the extreme fast-translation events are related to a low-pressure system across most of the continental U.S. that leads to westerly steering flow that enhances tropical cyclone movement. This study suggests that it might be useful to separate tropical cyclone events into fast-moving and slow-moving groups when examining the translational speed of North Atlantic tropical cyclones, instead of examining regional or global mean translational speed.
