Hurricane Iva (1976)
The 1976 Pacific hurricane season was a very deadly and costly season. Hurricanes Kathleen, Liza, and Madeline were the most notable storms this year. Hurricane Kathleen caused death and destruction in California and Arizona due to flooding. Hurricane Liza was the deadliest storm of the season when it killed over 600 people in Mexico. Hurricane Madeline is notable for being one of the most intense Pacific hurricanes at landfall. __TOC__ Season summary ImageSize = width:800 height:205 PlotArea = top:10 bottom:80 right:20 left:20 Legend = columns:3 left:30 top:58 columnwidth:270 AlignBars = early DateFormat = dd/mm/yyyy Period = from:01/06/1976 till:06/11/1976 TimeAxis = orientation:horizontal ScaleMinor = grid:black unit:month increment:1 start:01/06/1976 Colors = id:canvas value:gray(0.88) id:GP value:red id:TD value:rgb(0.38,0.73,1) legend:Tropical_Depression_=_≤38_mph_(≤62_km/h) id:TS value:rgb(0,0.98,0.96) legend:Tropical_Storm_=_39–7 ...

1974 Pacific Hurricane Season
The 1974 Pacific hurricane season featured one of the most active periods of tropical cyclones on record with five storms existing simultaneously. The season officially started May 15 in the eastern Pacific, and June 1 in the central Pacific, and lasted until November 30. These dates conventionally delimit the period of each year when most tropical cyclones form in the northeast Pacific Ocean. With 17 named storms and 11 hurricanes, this season was slightly above average. An additional tropical storm formed in the Central Pacific as well. The year also featured a period where six systems, Ione, Olive, Kirsten, Lorraine, Joyce, and Maggie, were all active at once on August 26, a very unusual occurrence. At the time, Olive was a Central Pacific storm that had weakened to a tropical depression while the other five were of at least tropical storm intensity simultaneously and remained so until early on August 27. Five storms were also active between t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wind Shear
Wind shear (or windshear), sometimes referred to as wind gradient, is a difference in wind speed and/or direction over a relatively short distance in the atmosphere. Atmospheric wind shear is normally described as either vertical or horizontal wind shear. Vertical wind shear is a change in wind speed or direction with a change in altitude. Horizontal wind shear is a change in wind speed with a change in lateral position for a given altitude. Wind shear is a microscale meteorological phenomenon occurring over a very small distance, but it can be associated with mesoscale or synoptic scale weather features such as squall lines and cold fronts. It is commonly observed near microbursts and downbursts caused by thunderstorms, fronts, areas of locally higher low-level winds referred to as low-level jets, near mountains, radiation inversions that occur due to clear skies and calm winds, buildings, wind turbines, and sailboats. Wind shear has significant effects on the control ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1976 Pacific Typhoon Season
The 1976 Pacific typhoon season has no official bounds; it ran year-round in 1976, but most tropical cyclones tend to form in the northwestern Pacific Ocean between June and December. These dates conventionally delimit the period of each year when most tropical cyclones form in the northwestern Pacific Ocean. The scope of this article is limited to the Pacific Ocean, north of the equator and west of the international date line. Storms that form east of the date line and north of the equator are called hurricanes; see 1976 Pacific hurricane season. Tropical Storms formed in the entire west pacific basin were assigned a name by the Joint Typhoon Warning Center. Tropical depressions in this basin have the "W" suffix added to their number. Tropical depressions that enter or form in the Philippine area of responsibility are assigned a name by the Philippine Atmospheric, Geophysical and Astronomical Services Administration or PAGASA. This can often result in the same storm having two na ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1976 Atlantic Hurricane Season
The 1976 Atlantic hurricane season featured only one fully tropical storm throughout both the Caribbean Sea and the Gulf of Mexico, a rare occurrence. The season officially began on June 1 and lasted until November 30. These dates conventionally delimit the period of each year when most tropical cyclones form in the Atlantic basin. However, the first system, a subtropical storm, developed in the Gulf of Mexico on May 21, several days before the official start of the season. The system spawned nine tornadoes in Florida, resulting in about $628,000 (1976 USD) in damage, though impact was minor otherwise. The season was near average, with ten tropical storm forming, of which six became hurricanes. Two of those six became major hurricanes, which are Category 3 or higher on the Saffir–Simpson scale. The strongest hurricane of the season was Hurricane Belle, which reached Category 3 intensity east of North Carolina. Belle later struck Long Island, New York, as a Category 1 h ...

Pacific Hurricane Season
A Pacific hurricane is a mature tropical cyclone that develops within the northeastern and central Pacific Ocean to the east of 180°W, north of the equator. For tropical cyclone warning purposes, the northern Pacific is divided into three regions: the eastern (North America to 140°W), central (140°W to 180°), and western (180° to 100°E), while the southern Pacific is divided into 2 sections, the Australian region (90E to 160°E) and the southern Pacific basin between 160°E and 120°W. Identical phenomena in the western north Pacific are called typhoons. This separation between the two basins has a practical convenience, however, as tropical cyclones rarely form in the central north Pacific due to high vertical wind shear, and few cross the dateline.

List Of Pacific Hurricanes
This is a list of notable Pacific hurricanes, subdivided by reason for notability. Notability means that it has met some criterion or achieved some statistic, or is part of a top ten for some superlative. It includes lists and rankings of Pacific hurricanes by different characteristics and impacts. Characteristics include extremes of location, such as the northernmost or most equator-ward formation or position of a tropical cyclone. Other characteristics include its central pressure, windspeed, category on the Saffir–Simpson scale, cyclogenesis outside of a normal hurricane season's timeframe, or storms that remain unnamed despite forming after tropical cyclone naming began in 1960. Another characteristic is how long a system lasted from formation to dissipation. These include the cost of damage, the number of casualties, as well as meteorological statistics such as rainfall point maximum, wind speed, and minimum pressure.

1972 Pacific Hurricane Season
The 1972 Pacific hurricane season was an ongoing event in tropical cyclone meteorology. There were few notable storms this year. Only one person was killed and storm effects were almost not serious at all. The most notable systems were Hurricane Celeste and Joanne. Celeste was the strongest storm of the season, and caused heavy damage to Johnston Atoll. Hurricane Joanne brought gale-force winds to the Continental United States and caused flooding in Arizona and northern Mexico, which killed one person. The only other system to directly impact land was Hurricane Annette. The season began on May 15, 1972, in the east Pacific, and on June 1, 1972, in the central Pacific. It ended on November 30, 1972. These dates conventionally delimit the period of time when tropical cyclones form in the east Pacific Ocean. This season had a below average number of storms. There were twenty tropical cyclones, four of which were in the central Pacific. Of those, four were tropical storms, eight were ...

Eyewall Replacement Cycle
In meteorology, eyewall replacement cycles, also called concentric eyewall cycles, naturally occur in intense tropical cyclones, generally with winds greater than , or major hurricanes ( Category 3 or above). When tropical cyclones reach this intensity, and the eyewall contracts or is already sufficiently small, some of the outer rainbands may strengthen and organize into a ring of thunderstorms—a new, outer eyewall—that slowly moves inward and robs the original, inner eyewall of its needed moisture and angular momentum. Since the strongest winds are in a tropical cyclone's eyewall, the storm usually weakens during this phase, as the inner wall is "choked" by the outer wall. Eventually the outer eyewall replaces the inner one completely, and the storm may re-intensify. The discovery of this process was partially responsible for the end of the U.S. government's hurricane modification experiment Project Stormfury. This project set out to seed clouds outside the eyewall, appa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
