2023 Pacific Hurricane Season
The 2023 Pacific hurricane season was an active and highly destructive Pacific hurricane season. In the Eastern Pacific basin (east of 140°W), 17 named storms formed; 10 of those became hurricanes, of which 8 strengthened into major hurricanesdouble the seasonal average. In the Central Pacific basin (between 140°W and the International Date Line), no tropical cyclones formed for the fourth consecutive season, though four entered into the basin from the east. Collectively, the season had an above-normal accumulated cyclone energy (ACE) value of approximately 168 units. This season saw the return of El Niño and its associated warmer sea surface temperatures in the basin, which fueled the rapid intensification of several powerful storms. It officially began on May 15, 2023 in the Eastern Pacific, and on June 1 in the Central; both ended on November 30. These dates, adopted by convention, historically describe the period in each year when most t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rapid Intensification
Rapid intensification (RI) is any process wherein a tropical cyclone strengthens very dramatically in a short period of time. Tropical cyclone forecasting agencies utilize differing thresholds for designating rapid intensification events, though the most widely used definition stipulates an increase in the maximum sustained winds of a tropical cyclone of at least in a 24-hour period. However, periods of rapid intensification often last longer than a day. About 20–30% of all tropical cyclones undergo rapid intensification, including a majority of tropical cyclones with peak wind speeds exceeding . Rapid intensification constitutes a major source of error for tropical cyclone forecasting, and its predictability is commonly cited as a key area for improvement. The specific physical mechanisms that underlie rapid intensification and the environmental conditions necessary to support rapid intensification are unclear due to the complex interactions between the environment surr ...

Baja California
Baja California, officially the Free and Sovereign State of Baja California, is a state in Mexico. It is the northwesternmost of the 32 federal entities of Mexico. Before becoming a state in 1952, the area was known as the North Territory of Baja California (). It has an area of (3.57% of the land mass of Mexico) and comprises the northern half of the Baja California peninsula, north of the 28th parallel, plus oceanic Guadalupe Island. The mainland portion of the state is bordered on the west by the Pacific Ocean; on the east by Sonora, the United States on the north and on the south by Baja California Sur. The state has an estimated population of 3,769,020 as of 2020, significantly higher than the sparsely populated Baja California Sur to the south, and similar to San Diego County, California, and Imperial County, California, to its north. Over 75% of the population lives in Mexicali (the state's capital city), Ensenada, or Tijuana (the state's largest city). Other impo ...

Hurricane Hilary
Hurricane Hilary was a large and powerful Pacific hurricane in August 2023 that brought torrential rainfall and gusty winds to the Pacific Coast of Mexico, the Baja California Peninsula, and the Southwestern United States, resulting in widespread flooding and mudslides. The cyclone was the eighth named storm, sixth hurricane, and fourth major hurricane of the 2023 Pacific hurricane season. Hilary originated from a tropical wave south of Mexico on August 16, and strengthened into a hurricane a day later while paralleling the southwest coast of Mexico. The hurricane underwent rapid intensification, reaching maximum sustained winds of 140 mph (220 km/h) and a central pressure of on August 18, making it a Category 4 on the Saffir-Simpson scale. After environmental conditions became unfavorable, Hilary weakened as it approached land, making landfall on August 20 as a tropical storm in San Quintín along the western Baja California peninsula ...

2023 Hawaii Wildfires
The 2023 Hawaii wildfires were a series of wildfires that broke out in early August 2023 in the U.S. state of Hawaii, predominantly on the island of Maui. The wind-driven fires prompted evacuations and caused widespread damage, killing at least 102 people and leaving two people missing in the town of Lahaina, Hawaii, Lahaina on Maui's northwest coast. The proliferation of the wildfires was attributed to dry, gusty conditions created by a strong high-pressure area north of Hawaii and Hurricane Dora (2023), Hurricane Dora to the south. An emergency declaration was signed on August 8, authorizing several actions, including activation of the Hawaii National Guard, appropriate actions by the director of the Hawaii Emergency Management Agency and the Administrator of Emergency Management, and the expenditure of state general revenue funds for relief of conditions created by the fires. By August 9, the state government of Hawaii issued a state of emergency for the entirety of the state ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gradient Wind
In atmospheric science, balanced flow is an idealisation of atmospheric motion. The idealisation consists in considering the behaviour of one isolated parcel of air having constant density, its motion on a horizontal plane subject to selected forces acting on it and, finally, steady-state conditions. Balanced flow is often an accurate approximation of the actual flow, and is useful in improving the qualitative understanding and interpretation of atmospheric motion. In particular, the balanced-flow speeds can be used as estimates of the wind speed for particular arrangements of the atmospheric pressure on Earth's surface. The momentum equations in natural coordinates Trajectories The momentum equations are written primarily for the generic trajectory of a packet of flow travelling on a horizontal plane and taken at a certain elapsed time called ''t''. The position of the packet is defined by the distance on the trajectory ''s''=''s''(''t'') which it has travelled by time ''t'' ...

Hawaiian Islands
The Hawaiian Islands () are an archipelago of eight major volcanic islands, several atolls, and numerous smaller islets in the Pacific Ocean, North Pacific Ocean, extending some from the Hawaii (island), island of Hawaii in the south to northernmost Kure Atoll. Formerly called the Sandwich Islands by Europeans, the present name for the archipelago is derived from the name of its largest island, Hawaii. The archipelago sits on the Pacific Plate. The islands are exposed peaks of a great undersea mountain range known as the Hawaiian–Emperor seamount chain, formed by volcano, volcanic activity over the Hawaiian hotspot. The islands are about from the nearest continent and are part of the Polynesia subregion of Oceania. The U.S. state of Hawaii occupies the archipelago almost in its entirety (including the mostly uninhabited Northwestern Hawaiian Islands), with the sole exception of Midway Atoll (a United States Minor Outlying Island).

Hurricane Dora (2023)
Hurricane Dora, also known as Typhoon Dora, was a longlived and powerful tropical cyclone that tracked across all three North Pacific tropical cyclone basins in August 2023. The fourth named storm, fourth hurricane, and second major hurricane of the 2023 Pacific hurricane season, Dora developed on July 31, from a tropical wave that had crossed over Central America from the North Atlantic, and became a tropical storm early the following day. During August 2–3, the system rapidly intensified to Category 4 strength. The same day, Dora moved into the Central Pacific basin from the East Pacific basin. Dora's annular structure deteriorated, leaving the system susceptible to dry air intrusions, and the hurricane passed south of Johnston Island. Dora weakened to Category 3 strength on the morning of August 10. The same day, southerly shear degraded the hurricane's structure as it shifted its course toward the west-northwest along the southwest edge of a high pressur ...

2016 Pacific Hurricane Season
The 2016 Pacific hurricane season was tied as the fifth-most active Pacific hurricane season on record, alongside the 2014 season. Throughout the course of the year, a total of 22 named storms, 13 hurricanes and six major hurricanes were observed within the basin. Although the season was very active, it was considerably less active than the previous season, with large gaps of inactivity at the beginning and towards the end of the season. It officially started on May 15 in the Eastern Pacific (north of the Equator and east 140°W), and on June 1 in the Central Pacific (from 140°W to the International Date Line); they both ended on November 30. These dates conventionally delimit the period of each year when most tropical cyclones form in these regions of the Pacific Ocean. However, tropical development is possible at any time of the year, as demonstrated by the formation of Hurricane Pali on January 7, the earliest Central Pacific tropical cyclone on record. Afte ...
