Hurricane Agatha
Hurricane Agatha was the strongest hurricane to make landfall along the Pacific coast of Mexico in the month of May since records began in 1949. The first named storm and the first hurricane of the 2022 Pacific hurricane season, Agatha originated from a surface trough south of the Gulf of Tehuantepec. It steadily organized into a tropical depression early on May 28 and within hours intensified into Tropical Storm Agatha. Amid favorable environmental conditions, the cyclone underwent rapid intensification on May 29, strengthening into a Category 2 hurricane and reaching peak winds of . Though the storm moved west-northwest early on, it curved toward the northeast in response to weakening high pressure over Mexico. On the afternoon of May 30, the hurricane made landfall just west of Puerto Ángel, Oaxaca, with slightly weaker winds of . Agatha weakened rapidly as it moved inland, and soon dissipated. Heavy rain brought by the storm triggered landslides and flas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Microwave Imaging
Microwave imaging is a science which has been evolved from older detecting/locating techniques (e.g., radar) in order to evaluate hidden or embedded objects in a structure (or media) using electromagnetic (EM) waves in microwave regime (i.e., ~300 MHz-300 GHz). Engineering and application oriented microwave imaging for non-destructive testing is called #Microwave testing, microwave testing, see below. Microwave imaging techniques can be classified as either quantitative or qualitative. Quantitative imaging techniques (are also known as inverse scattering methods) give the electrical (i.e., electrical and magnetic property distribution) and geometrical parameters (i.e., shape, size and location) of an imaged object by solving a nonlinear inverse problem. The nonlinear inverse problem is converted into a linear inverse problem (i.e., Ax=b where A and b are known and x (or image) is unknown) by using Born or distorted Born approximations. Despite the fact that direct matrix i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lagunas De Chacahua National Park
The Lagunas de Chacahua National Park (), created in 1937, is a national park located in the Municipality of Villa de Tututepec de Melchor Ocampo in the Mexican state of Oaxaca, about 54 km west of Puerto Escondido, near a village called Zapotalito. It can be reached via Federal Highway 200 or by boat from Puerto Escondido. It is located between the towns of Santiago Jamiltepec and Puerto Escondido. The park encompasses 132.73 square kilometres, about 30 km2 of which is taken by various lagoons such as the ‘’’Laguna de Chacahua,’’’ ‘’’Laguna de La Pastoria,’’’ and Laguna Las Salinas.

Salina Cruz
Salina Cruz is a major seaport on the Pacific Ocean, Pacific coast of the List of states of Mexico, Mexican state of Oaxaca. It is the state's fourth-largest city and is the municipal seat of the Municipalities of Oaxaca, municipality of the same name. It is part of the Tehuantepec District in the west of the Istmo de Tehuantepec, Istmo Region. The city had a 2020 census population of 76,660, while its municipality, with an area of had a population of 84,438, the state's fifth-largest municipality in population. The port was developed in the late 19th century due to its location at the southern terminus of the Tren Interoceánico, which carried freight across the Isthmus of Tehuantepec. History Salina Cruz was founded in 1522 by the Spanish, under whose command Pedro de Alvarado came. It was given the name "Salina de la Santa Cruz" as its official foundation day was the Catholic day of the holy cross. Salina Cruz is situated near the mouth of the Tehuantepec River, Río T ...

Tropical Cyclone Watches And Warnings
Tropical cyclone warnings and watches are alerts issued by national weather forecasting bodies to coastal areas threatened by the imminent approach of a tropical cyclone of tropical storm or hurricane intensity. They are notices to the local population and civil authorities to make appropriate preparation for the cyclone, including evacuation of vulnerable areas where necessary. It is important that interests throughout the area of an alert make preparations to protect life and property, and do not disregard it on the strength of the detailed forecast track. Western hemisphere New tropical cyclone position and forecast information is available at least every twelve hours in the Southern Hemisphere and at least every six hours in the Northern Hemisphere from Regional Specialized Meteorological Centers and Tropical Cyclone Warning Centers. In conjunction with the National Hurricane Center, the national meteorological and hydrological services of Central America, the northern Atla ...

Tropical Storm Alex (2022)
Tropical Storm Alex was a strong and fast moving tropical storm that caused flash flooding in western Cuba and South Florida while developing into the first named storm of the 2022 Atlantic hurricane season. Alex originated from a broad area of low pressure partially related to the remnants of Hurricane Agatha in the Eastern Pacific. The National Hurricane Center (NHC) initiated advisories on it as '' Potential Tropical Cyclone One'' over the eastern Yucatán Peninsula on June 2. Wind shear and dry air kept the system disorganized until after it crossed Florida two days later. Finally, on June 5, the system became sufficiently organized and was named ''Alex'' while located north of Grand Bahama Island. Later that same day, Alex's winds briefly strengthened to . The storm brought rain and strong winds to Bermuda on June 6, before becoming a post-tropical cyclone that same day. Alex formed four days after the official start of the season, making the 2022 Atlantic hu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
2022 Atlantic Hurricane Season
The 2022 Atlantic hurricane season was a destructive and deadly Atlantic hurricane season. Despite having an average number of named storms and below average amount of major hurricanes, it became the fourth-costliest Atlantic hurricane season on record, behind only 2024, 2005, and 2017, mostly due to Hurricane Ian. The season officially began on June 1, and ended on November 30. These dates, adopted by convention, historically describe the period in each year when most subtropical or tropical cyclogenesis occurs in the Atlantic Ocean. This year's first Atlantic named storm, Tropical Storm Alex, developed four days after the start of the season, making this the first season since 2014 not to have a pre-season named storm. Two systems developed on July 1. Tropical Storm Bonnie formed and made landfall near the Costa Rica–Nicaragua border. It then crossed over into the Pacific basin, becoming the first to survive the crossover from the Atlantic to the Pacific ...

Isthmus Of Tehuantepec
The Isthmus of Tehuantepec () is an isthmus in Mexico. It represents the shortest distance between the Gulf of Mexico and the Pacific Ocean. Before the opening of the Panama Canal, it was a major overland transport route known simply as the Tehuantepec Route. The name is taken from the town of Santo Domingo Tehuantepec in the state of Oaxaca; this was derived from the Nahuatl term (" jaguar mountain"). Geography The isthmus includes the part of Mexico lying between the 94th and 96th meridians west longitude, or the southeastern parts of Veracruz and Oaxaca, including small areas of Chiapas and Tabasco. The states of Tabasco and Chiapas are east of the isthmus, with Veracruz and Oaxaca on the west. At its narrowest point, the isthmus is across from gulf to gulf, or to the head of Laguna Superior on the Pacific coast. The Sierra Madre del Sur mountain range breaks down at this point into a broad, plateau-like ridge, whose elevation, at the highest point reached by the ...

Central Dense Overcast
The central dense overcast, or CDO, of a tropical cyclone or strong subtropical cyclone is the large central area of thunderstorms surrounding its circulation center, caused by the formation of its eyewall. It can be round, angular, oval, or irregular in shape. This feature shows up in tropical cyclones of tropical storm or hurricane strength. How far the center is embedded within the CDO, and the temperature difference between the cloud tops within the CDO and the cyclone's eye, can help determine a tropical cyclone's intensity with the Dvorak technique. Locating the center within the CDO can be a problem with strong tropical storms and minimal hurricanes as its location can be obscured by the CDO's high cloud canopy. This center location problem can be resolved through the use of microwave satellite imagery. After a cyclone strengthens to around hurricane intensity, an eye appears at the center of the CDO, defining its center of low pressure and its cyclonic wind field. Tropi ...

Eye (cyclone)
The eye is a region of mostly calm weather at the center of a tropical cyclone. The eye of a storm is a roughly circular area, typically in diameter. It is surrounded by the eyewall, a ring of towering thunderstorms where the most severe weather and highest winds of the cyclone occur. The cyclone's lowest barometric pressure occurs in the eye and can be as much as 15 percent lower than the pressure outside the storm. In strong tropical cyclones, the eye is characterized by light winds and clear skies, surrounded on all sides by a towering, symmetric eyewall. In weaker tropical cyclones, the eye is less well defined and can be covered by the central dense overcast, an area of high, thick clouds that show up brightly on satellite imagery. Weaker or disorganized storms may also feature an eyewall that does not completely encircle the eye or have an eye that features heavy rain. In all storms, however, the eye is where the barometer reading is lowest. Structure A typical tropi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hurricane Hunters
Hurricane hunters, typhoon hunters, or cyclone hunters are aircrews that fly into tropical cyclones to gather weather data. In the United States, the organizations that fly these missions are the United States Air Force Reserve's 53rd Weather Reconnaissance Squadron and the National Oceanic and Atmospheric Administration's Hurricane Hunters. Such missions have also been flown by Navy units and other Air Force and NOAA units. Other organizations also fly these missions, such as Government Flying Service Hong Kong. The first crewed flight into a hurricane happened in 1943 when a pilot-trainer flew into a Category 1 hurricane near Galveston, Texas on a bet. In the past, before satellites were used to find tropical storms, military aircraft flew routine weather reconnaissance tracks to detect formation of tropical cyclones. While modern satellites have improved the ability of meteorologists to detect cyclones before they form, only aircraft are able to measure the interior ba ...
