Hurricane Mitch in the context of 2007 Atlantic hurricane season

Geophysical fluid dynamics, in its broadest meaning, is the application of fluid dynamics to naturally occurring flows, such as lava, oceans, and atmospheres, on Earth and other planets.

Two physical features that are common to many of the phenomena studied in geophysical fluid dynamics are rotation of the fluid due to the planetary rotation and stratification (layering).

Hurricane Fifi, later known as Hurricane Orlene, was a catastrophic tropical cyclone that killed over 8,000 people in Honduras in September 1974, ranking it as the third deadliest Atlantic hurricane on record, only behind Hurricane Mitch in 1998, and the 1780 hurricane. Fifi is also the first billion-dollar hurricane not to make landfall in the United States. Originating from a strong tropical wave on September 14, the system steadily tracked west-northwestward through the eastern Caribbean. On September 16, the depression intensified into Tropical Storm Fifi just off the coast of Jamaica. The storm quickly intensified into a hurricane the following afternoon and attained its peak intensity on September 18 as a strong Category 2 hurricane. Maintaining hurricane intensity, Fifi brushed the northern coast of Honduras before making landfall in Belize the following day. The storm quickly weakened after landfall, becoming a depression late on September 20. Continuing westward, the former hurricane began to interact with another system in the eastern Pacific.

Early on September 22, Fifi re-attained tropical storm status before fully regenerating into a new tropical cyclone, Tropical Storm Orlene. Orlene traveled in an arced path toward Mexico while quickly intensifying into a Category 2 hurricane before landfall. The storm weakened after landfall and dissipated fully during the afternoon of September 24 over the mountains of Mexico. Along its path, Fifi impacted nine countries, leaving over 8,200 fatalities and $1.8 billion (1974 USD; $11.5 billion 2025 USD) in damages. Most of the loss of life and damage occurred in Honduras where rainfall from the hurricane, peaking around 24 in (610 mm), triggered widespread flash flooding and mudslides.

Hurricane Dean was a powerful and destructive tropical cyclone that became the strongest of the 2007 Atlantic hurricane season. It ties with Hurricane Mitch for the tenth most intense Atlantic hurricane by atmospheric pressure. Additionally, it made the fifth most intense landfall in the basin by central pressure. A Cape Verde hurricane that formed on August 13, 2007, Dean took a west-northwest path from the eastern Atlantic Ocean through the Saint Lucia Channel and into the Caribbean Sea. It strengthened into a major hurricane, reaching Category 5 status on the Saffir–Simpson scale before passing just south of Jamaica on August 20. The storm made landfall on the Yucatán Peninsula on August 21 at peak intensity. It crossed the peninsula and emerged into the Bay of Campeche weakened, but still remained a hurricane. It strengthened briefly before making a second landfall near Tecolutla in the Mexican state of Veracruz on August 22. Dean drifted to the northwest, weakening into a remnant low which dissipated uneventfully over the southwestern United States. Dean was the second-most intense tropical cyclone worldwide of 2007 in terms of pressure, only behind Cyclone George in the Australian region, and tied with Felix as the most intense worldwide in terms of 1-minute sustained winds.

The hurricane's intense winds, waves, rains and storm surge were responsible for at least 45 deaths across ten countries and caused estimated damages of US$1.66 billion. First impacting the islands of the Lesser Antilles, Dean's path through the Caribbean devastated agricultural crops, particularly those of Martinique and Jamaica. Upon reaching Mexico, Hurricane Dean was a Category 5 storm, but it missed major population centers and its exceptional Category 5 strength landfall caused no deaths and less damage than in the Caribbean islands it passed as a Category 2 storm.
