While many studies examine the synoptic and dynamic features associated with the growth of tropical cyclones or their landfall, relatively few (Fedorova et al.) examine several case studies of weaker storms near the equator that give rise to fog and mist events over Northeast Brazil. These events can have serious consequences for aerospace operations. In these cases, it was found that the tropical cyclones or disturbances do not come ashore directly, but it is the indirect influence caused by secondary circulations that lead to the formation of fog and mist events. Also, tropical cyclones such as tropical storms and hurricanes generally emerge from tropical disturbances. Over the Atlantic region these disturbances occur with some regularity emanating from formation regions over Africa (African Easterly Waves -AEWs). Reyes and Shen use this quasi-periodicity to develop algorithms to forecast their occurrence using recurrence theory. These results show some promise in extending the lead time for the forecasting of the tropical cyclone "seeds".Other parts of the world, such as the countries of the Northwest Pacific, are also vulnerable to the occurrence of tropical cyclones. A review by Wu and Conde summarizes the previous research done by the authors and collaborators involving the response of coastal ocean dynamics to tropical cyclone occurrence for variables such as sea surface temperature, sea surface salinity, storm surge simulation, and extreme rainfall. They also propose three research paths for future work that involves observational, dynamic, and model studies in order to improve the understanding of the future threat these regions may face due to tropical cyclones.Satellite techniques are often used to determine the intensity of tropical cyclones using the area of cold cloud tops near the center as well as storm feature shapes as determined using visible or infrared imagery (the Dvorak technique). The work of Yurchak proposes using the character of the spiral rainbands as derived from not only satellite techniques, but augmenting this with ground and aircraft-based RADAR to determine the shape of the spiral bands. This information can be used to develop a hyperbolic-logarithmic streamline equation that ultimately relates the model to maximum wind speed.Lastly, it was a pleasure to edit this book and work with all the authors and the staff of IntechOpen. The process was rather smooth. I am grateful to all the authors for their contributions, and the staff at IntechOpen for their hard work in keeping the process moving along. This is the third such project that I've been involved with and the experience has been good each time. Finally, it is my hope that the tropical meteorology community finds this book to be a useful resource for augmenting their own studies as well as providing a basis for future research.
