Hurricane Fern (1967)
The 1967 Atlantic hurricane season was the first Atlantic hurricane season to be part of the modern-day satellite era. With 13 named storms, it was an above average season in terms of named storms, slightly above average in terms of hurricanes (6), and below average in terms of major hurricanes, with only one; Beulah. The season began on June 1, 1967 and ended on November 30, 1967, which delimits the time boundaries when tropical cyclones in the North Atlantic Ocean typically form. The first depression originated on June 10, and the final storm – Heidi – lost tropical characteristics on October 31. Hurricane Beulah – the strongest storm of the season – was also the most damaging, causing 59 deaths and $235 million in damage (1967 USD) along its two-week-long path. Beulah formed on September 5 and soon after crossed southern Martinique into the Caribbean Sea. On the island, it dropped of rainfall in Les Anses-d'Arlet, causing severe ...

Hurricane Beulah
Hurricane Beulah was the second tropical storm, second hurricane, and only major hurricane during the 1967 Atlantic hurricane season. It tracked through the Caribbean, struck the Yucatán Peninsula of Mexico as a major hurricane, and moved west-northwestward into the Gulf of Mexico, briefly gaining Category 5 intensity. It was the strongest hurricane during the 1967 Atlantic hurricane season. The hurricane made landfall just north of the mouth of the Rio Grande River as a Category 3 hurricane. It spawned 115 tornadoes across Texas, which established a new record for the highest amount of tornadoes produced by a tropical cyclone. Due to its slow movement over Texas, Beulah led to significant flooding. Throughout its path, at least 59 people were killed and total damage reached $234.6 million (1967 USD), of which $200 million occurred in the United States, $26.9 million occurred in Mexico, and $7.65 million occurred in the eastern Caribbean.

Senegal
Senegal,; Wolof: ''Senegaal''; Pulaar: 𞤅𞤫𞤲𞤫𞤺𞤢𞥄𞤤𞤭 (Senegaali); Arabic: السنغال ''As-Sinighal'') officially the Republic of Senegal,; Wolof: ''Réewum Senegaal''; Pulaar : 𞤈𞤫𞤲𞤣𞤢𞥄𞤲𞤣𞤭 𞤅𞤫𞤲𞤫𞤺𞤢𞥄𞤤𞤭 (Renndaandi Senegaali); Arabic: جمهورية السنغال ''Jumhuriat As-Sinighal'') is a country in West Africa, on the Atlantic Ocean coastline. Senegal is bordered by Mauritania to the north, Mali to the east, Guinea to the southeast and Guinea-Bissau to the southwest. Senegal nearly surrounds the Gambia, a country occupying a narrow sliver of land along the banks of the Gambia River, which separates Senegal's southern region of Casamance from the rest of the country. Senegal also shares a maritime border with Cape Verde. Senegal's economic and political capital is Dakar. Senegal is notably the westernmost country in the mainland of the Old World, or Afro-Eurasia.

Dakar
Dakar ( ; ; wo, Ndakaaru) (from daqaar ''tamarind''), is the capital and largest city of Senegal. The city of Dakar proper has a population of 1,030,594, whereas the population of the Dakar metropolitan area is estimated at 3.94 million in 2021. The area around Dakar was settled in the 15th century. The Portuguese established a presence on the island of Gorée off the coast of Cap-Vert and used it as a base for the Atlantic slave trade. France took over the island in 1677. Following the abolition of the slave trade and French annexation of the mainland area in the 19th century, Dakar grew into a major regional port and a major city of the French colonial empire. In 1902, Dakar replaced Saint-Louis as the capital of French West Africa. From 1959 to 1960, Dakar was the capital of the short-lived Mali Federation. In 1960, it became the capital of the independent Republic of Senegal. History The Cap-Vert peninsula was settled no later than the 15th century, by the Lebu peop ...

Cold Front
A cold front is the leading edge of a cooler mass of air at ground level that replaces a warmer mass of air and lies within a pronounced surface trough of low pressure. It often forms behind an extratropical cyclone (to the west in the Northern Hemisphere, to the east in the Southern), at the leading edge of its cold air advection pattern—known as the cyclone's dry "conveyor belt" flow. Temperature differences across the boundary can exceed from one side to the other. When enough moisture is present, rain can occur along the boundary. If there is significant instability along the boundary, a narrow line of thunderstorms can form along the frontal zone. If instability is weak, a broad shield of rain can move in behind the front, and evaporative cooling of the rain can increase the temperature difference across the front. Cold fronts are stronger in the fall and spring transition seasons and are weakest during the summer. Development of cold fronts A cold front occurs wh ...

Intertropical Convergence Zone
The Intertropical Convergence Zone (ITCZ ), known by sailors as the doldrums or the calms because of its monotonous windless weather, is the area where the northeast and the southeast trade winds converge. It encircles Earth near the thermal equator though its specific position varies seasonally. When it lies near the geographic Equator, it is called the near-equatorial trough. Where the ITCZ is drawn into and merges with a monsoonal circulation, it is sometimes referred to as a monsoon trough, a usage that is more common in Australia and parts of Asia. Meteorology The ITCZ was originally identified from the 1920s to the 1940s as the ''Intertropical Front'' (''ITF''), but after the recognition in the 1940s and the 1950s of the significance of wind field convergence in tropical weather production, the term ''Intertropical Convergence Zone'' (''ITCZ'') was then applied. The ITCZ appears as a band of clouds, usually thunderstorms, that encircle the globe near the Equator. In the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tropical Cyclogenesis
Tropical cyclogenesis is the development and strengthening of a tropical cyclone in the atmosphere. The mechanisms through which tropical cyclogenesis occurs are distinctly different from those through which temperate cyclogenesis occurs. Tropical cyclogenesis involves the development of a warm-core cyclone, due to significant convection in a favorable atmospheric environment. Tropical cyclogenesis requires six main factors: sufficiently warm sea surface temperatures (at least ), atmospheric instability, high humidity in the lower to middle levels of the troposphere, enough Coriolis force to develop a low-pressure center, a pre-existing low-level focus or disturbance, and low vertical wind shear. Tropical cyclones tend to develop during the summer, but have been noted in nearly every month in most basins. Climate cycles such as ENSO and the Madden–Julian oscillation modulate the timing and frequency of tropical cyclone development. There is a limit on tropical cyclone i ...

Robert Simpson (meteorologist)
Robert Homer Simpson (November 19, 1912 – December 18, 2014) was an American meteorologist, hurricane specialist, first director of the National Hurricane Research Project (NHRP) from 1955 to 1959, and a former director (1967–1974) of the National Hurricane Center (NHC). He was the co-developer of the Saffir–Simpson Hurricane Scale with Herbert Saffir. His wife was Joanne Simpson. Early life Born in Corpus Christi, Texas, Robert Simpson survived the devastating landfall of the 1919 Florida Keys hurricane at age six; one of his family members drowned. Simpson graduated with honors from the Corpus Christi high school in 1929. Fascinated by the weather, he went on to get a Bachelor of Science degree in physics from Southwestern University in 1933, and a Master of Science degree in physics from Emory University in 1935. Finding no work as a physicist during the Great Depression, he taught music in Texas high schools. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gordon Dunn (meteorologist)
Gordon Glover "Slinger" Dunn (April 16, 1912 – July 26, 1964) was an American discus thrower who won a silver medal at the 1936 Summer Olympics, a U.S. Navy lieutenant, and former mayor of Fresno, California from 1949-1957. Godron Dunn was born April 16, 1912, to William F. Dunn and Olive C. Glover in Portland, Oregon. Dunn's father, William F. Dunn once served as the deputy city clerk for Fresno. Shortly after Dunn was born, the family moved home to Fresno, where the Dunn family had lived since the 1880s. Dunn's paternal grandfather, Thomas Dunn, was a pioneer resident of Fresno, a former councilmember, and potential mayoral candidate. Dunn Avenue is named for his grandfather, Thomas Dunn. Dunn graduated from Fresno High School and attended Stanford University. Dunn's penchant for track and field, and specifically discus throw, allowed him to continue these sports through both high school and college. Earlier in 1934 he won the NCAA and IC4A titles. After college, Dunn remai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Atlantic Basin
The Atlantic Ocean is the second-largest of the world's five oceans, with an area of about . It covers approximately 20% of Earth's surface and about 29% of its water surface area. It is known to separate the "Old World" of Africa, Europe and Asia from the "New World" of the Americas in the European perception of the World. The Atlantic Ocean occupies an elongated, S-shaped basin extending longitudinally between Europe and Africa to the east, and North and South America to the west. As one component of the interconnected World Ocean, it is connected in the north to the Arctic Ocean, to the Pacific Ocean in the southwest, the Indian Ocean in the southeast, and the Southern Ocean in the south (other definitions describe the Atlantic as extending southward to Antarctica). The Atlantic Ocean is divided in two parts, by the Equatorial Counter Current, with the North(ern) Atlantic Ocean and the South(ern) Atlantic Ocean split at about 8°N. Scientific explorations of the Atlantic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tropical Cyclone
A tropical cyclone is a rapidly rotating storm system characterized by a low-pressure center, a closed low-level atmospheric circulation, strong winds, and a spiral arrangement of thunderstorms that produce heavy rain and squalls. Depending on its location and strength, a tropical cyclone is referred to by different names, including hurricane (), typhoon (), tropical storm, cyclonic storm, tropical depression, or simply cyclone. A hurricane is a strong tropical cyclone that occurs in the Atlantic Ocean or northeastern Pacific Ocean, and a typhoon occurs in the northwestern Pacific Ocean. In the Indian Ocean, South Pacific, or (rarely) South Atlantic, comparable storms are referred to simply as "tropical cyclones", and such storms in the Indian Ocean can also be called "severe cyclonic storms". "Tropical" refers to the geographical origin of these systems, which form almost exclusively over tropical seas. "Cyclone" refers to their winds moving in a circle, whirling round ...
