The Tropical Cyclones Portal

A tropical cyclone is a storm system characterized by a large low-pressure center, a closed low-level circulation and a spiral arrangement of numerous thunderstorms that produce strong winds and heavy rainfall. Tropical cyclones feed on the heat released when moist air rises, resulting in condensation of water vapor contained in the moist air. They are fuelled by a different heat mechanism than other cyclonic windstorms such as nor'easters, European windstorms and polar lows, leading to their classification as "warm core" storm systems. Most tropical cyclones originate in the doldrums near the Equator, approximately 10 degrees away.

The term "tropical" refers to both the geographic origin of these systems, which form almost exclusively in tropical regions of the globe, as well as to their formation in maritime tropical air masses. The term "cyclone" refers to such storms' cyclonic nature, with anticlockwise rotation in the Northern Hemisphere and clockwise rotation in the Southern Hemisphere. Depending on its location and intensity, a tropical cyclone may be referred to by names such as "hurricane", "typhoon", "tropical storm", "cyclonic storm", "tropical depression" or simply "cyclone".

Zorbas at peak intensity over the Ionian Sea

Cyclone Zorbas, or Medicane Zorbas, was the first officially documented Mediterranean tropical-like cyclone, or medicane, since Cyclone Numa in 2017. Zorbas originated as an extratropical cyclone in the eastern Mediterranean Sea. Warm sea surface temperatures allowed the system to quickly deepen and transition into a tropical cyclone. Zorbas intensified as it headed northward towards Greece, finally reaching its peak intensity with maximum sustained winds of 120 km/h (75 mph) and a minimum central pressure of 987 mbar (29.15 inHg) on September 29.

Heavy rain and flash flooding from Zorbas killed 5 people in Tunisia. One person was killed and two were declared missing in Greece. The storm was estimated to have caused millions of dollars (2018 USD) in damages. ( Full article...)

The Atlantic hurricane reanalysis project of the National Oceanic and Atmospheric Administration seeks to correct and add new information about past North Atlantic hurricanes. It was started around 2000 to update HURDAT, the official hurricane database for the Atlantic Basin, which has become outdated since its creation due to various systematic errors introduced into the database over time. This effort has involved reanalyses of ship observations from the International Comprehensive Ocean-Atmosphere Data Set (ICOADS) as well as reanalyses done by other researchers over the years. It has been ongoing as of 2016, and should last another four years. ( Full article...)

Four Southern Hemisphere Tropical Cyclones (2003).jpg
A train of four tropical cyclones is lined up in the southern Indian Ocean east of Madagascar (left) on February 12, 2003. This true-color image of the storms was made from observations collected by alternating passes of the Aqua and Terra satellites. The cyclones pictured are (west to east) Gerry, Hape, Isha, and Fiona of the 2003 Southwest Indian cyclone season. Terra satellite passed over this area in the morning, moving east to west, and contributing the first and third chunks of the image (from right to left). Aqua satellite passed over in the afternoon, also moving east to west, contributing the second and fourth chunks.

1969 Atlantic hurricane season summary map.png

The 1969 Atlantic hurricane season was the most active Atlantic hurricane season since the 1933 season, and was the final year of the most recent positive Atlantic multidecadal oscillation (AMO) era. The hurricane season officially began on June 1, and lasted until November 30. The season had the highest number of systems reach hurricane status – twelve – in a single season, until that record was surpassed in 2005. The season was above-average despite an El Niño, which typically suppresses activity in the Atlantic Ocean, while increasing tropical cyclone activity in the Pacific Ocean. Activity began with a series of five tropical depressions, the first of which developed on May 29. The third system in that series, Tropical Depression Seven, caused extensive flooding in Cuba and Jamaica in early June. The final in the series formed on July 25, the same day that Tropical Storm Anna developed. Neither the former nor latter caused significant impact on land. Later in the season, Tropical Depression Twenty-Nine caused severe local flooding in the Florida Panhandle and southwestern Georgia in September.

The most significant storm of the season was Hurricane Camille, which peaked as a Category 5 hurricane on August 17 and devastated the Gulf Coast of the United States upon striking Mississippi the next day. Strong winds and storm surge heights especially impacted Mississippi and Louisiana. Later in its duration, the storm caused severe flooding Virginia and West Virginia. Camille alone was responsible for 259 deaths and $1.43 billion. It was the costliest United States hurricane at the time, until Hurricane Agnes in 1972. In early September, Hurricane Francelia caused deadly floods in Central America, with 271 people killed in Central America. Hurricane Inga had the third longest duration of an Atlantic tropical cyclone. The last storm, Hurricane Martha, was the only known tropical cyclone to make landfall in Panama. Martha caused minor flooding in the former and Costa Rica. Overall, the systems of the season collectively caused 535 deaths and over $1.5 billion in losses. ( Full article...)

Track map of all the tropical depressions (Heta, Ivy, 10F/22P) monitored by the Joint Typhoon Warning Center during the season

The 2003–04 South Pacific cyclone season was a below-average season with only three tropical cyclones occurring within the South Pacific to the east of 160°E. The season officially ran from November 1, 2003 to April 30, 2004 with the first disturbance of the season forming on December 4 and the last disturbance dissipating on April 23. This is the period of the year when most tropical cyclones form within the South Pacific Ocean.

During the season at least 16 people were killed from tropical disturbances whilst overall damage was estimated at $218 million (2004 USD; $299 million 2021 USD). The most damaging tropical disturbance was Cyclone Heta which caused at least $211 million (2004 USD; $289 million 2021 USD) in damage to six different countries and left three dead. The deadliest tropical disturbance of the season was Tropical Depression 10F, which was responsible for eleven deaths and caused $2.74 million (2004 USD; $3.75 million 2021 USD) in damage. Cyclone Ivy also caused 2 deaths and caused $4.17 million (2004 USD; $5.72 million 2021 USD) worth of damage to Vanuatu. As a result of the impacts caused by Heta and Ivy, the names were retired from the tropical cyclone naming lists. ( Full article...)
