South Pacific Tropical Cyclone
A South Pacific tropical cyclone is a non- frontal, low pressure system that has developed, within an environment of warm sea surface temperatures and little vertical wind shear aloft in the South Pacific Ocean. Within the Southern Hemisphere there are officially three areas where tropical cyclones develop on a regular basis, these areas are the South-West Indian Ocean between Africa and 90°E, the Australian region between 90°E and 160°E and the South Pacific basin between 160°E and 120°W. The South Pacific basin between 160°E and 120°W is officially monitored by the Fiji Meteorological Service and New Zealand's MetService, while others like the Australian Bureau of Meteorology and the United States National Oceanic and Atmospheric Administration also monitor the basin. Each tropical cyclone year within this basin starts on July 1 and runs throughout the year, encompassing the tropical cyclone season which runs from November 1 and lasts until April 30 each season.

Weather Front
A weather front is a boundary separating air masses for which several characteristics differ, such as air density, wind, temperature, and humidity. Disturbed and unstable weather due to these differences often arises along the boundary. For instance, cold fronts can bring bands of thunderstorms and cumulonimbus precipitation or be preceded by squall lines, while warm fronts are usually preceded by stratiform precipitation and fog. In summer, subtler humidity gradients known as dry lines can trigger severe weather. Some fronts produce no precipitation and little cloudiness, although there is invariably a wind shift. Cold fronts generally move from west to east, whereas warm fronts move poleward, although any direction is possible. Occluded fronts are a hybrid merge of the two, and stationary fronts are stalled in their motion. Cold fronts and cold occlusions move faster than warm fronts and warm occlusions because the dense air behind them can lift as well as push the warme ...

Tropics
The tropics are the regions of Earth surrounding the equator, where the sun may shine directly overhead. This contrasts with the temperate or polar regions of Earth, where the Sun can never be directly overhead. This is because of Earth's axial tilt; the width of the tropics (in latitude) is twice the tilt. The tropics are also referred to as the tropical zone and the torrid zone (see geographical zone). Due to the overhead sun, the tropics receive the most solar energy over the course of the year, and consequently have the highest temperatures on the planet. Even when not directly overhead, the sun is still close to overhead throughout the year, therefore the tropics also have the lowest seasonal variation on the planet; "winter" and "summer" lose their temperature contrast. Instead, seasons are more commonly divided by precipitation variations than by temperature variations. The tropics maintain wide diversity of local climates, such as rain forests, monsoons, sa ...

1973–74 South Pacific Cyclone Season
The 1973–74 South Pacific cyclone season was an inactive season. In tropical cyclones, it was an average season, but in strength, it was very inactive, with only two severe tropical cyclones. Systems Tropical Cyclone SP7301 Severe Tropical Cyclone Natalie–Lottie This storm initially formed as Natalie, then moved into the Australian region on the same day. Later, it moved back into the South Pacific and was renamed Lottie. High seas caused the ship Uluilakeba to capsize killing more than 85 people. This makes Lottie one of the deadliest tropical cyclones in region in recent decades. Tropical Cyclone Monica Tropical Cyclone Nessie Tropical Cyclone Vera Severe Tropical Cyclone Pam Tropical Cyclone Rebecca Rebecca was thought to have had a complex evolution with two low-level circulation centres. It had peak 10-minute sustained windspeeds of and a minimum pressure of , before it dissipated during February 28. Tropical Cyclone Zoe Tropical Cyclone A ...

1970–71 South Pacific Cyclone Season
The 1970–71 South Pacific cyclone season, in terms of severe tropical cyclones, was the least active season on record, with none of its six storms strengthening above Category 2 tropical cyclone intensity. It was a below average season, beginning late and ending early. The season officially began on November 15 and ended on April 30, but the first storm formed a month after that, on December 15. __TOC__ Seasonal summary ImageSize = width:825 height:260 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:01/10/1970 till:01/05/1971 TimeAxis = orientation:horizontal ScaleMinor = grid:black unit:month increment:1 start:01/10/1970 Colors = id:canvas value:gray(0.88) id:GP value:red id:TDi value:rgb(0,0.52,0.84) legend:Tropical_Disturbance id:TD value:rgb(0.43,0.76,0.92) legend:Tropical_Depression id:C1 value:rgb(0.3,1,1) legend:Category_1_=_63-87_k ...

1969–70 South Pacific Cyclone Season
The 1969–70 South Pacific cyclone season was a very inactive season, featuring only seven disturbances, five tropical cyclones, and two severe tropical cyclones. The season featured only one landfalling storm, Cyclone Dawn. Dawn formed very late, on February 10, and the last storm, Tropical Depression Isa, dissipated early, on April 19. On January 2, a tropical low developed onto a weak depression on the Coral Sea.

1940s South Pacific Cyclone Seasons
The following is a list of all reported tropical cyclones within the South Pacific Ocean to the east of 160°E after the start of World War II in September 1939 and before the start of the 1950s decade. __TOC__ Background During the decade, meteorology in the Pacific rapidly developed after Britain, France and their dependent territories including Australia, Fiji, New Caledonia and New Zealand, declared war on Germany during September 1939. In particular, the New Zealand's Meteorological Service also took control of the Apia Observatory and created a facility at Lacuala Bay in Suva, Fiji during 1940. Meteorological operations were also started at the Nadi Airport by the United States Army Air Forces Meteorological Unit during 1942. During 1946, the Nadi military establishment was converted to a civilian unit, before the forecasting unit at Lacuala Bay was merged with the Nadi weather office during the following year. At this time, the Nadi Weather Office (NWO) primarily provid ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
