The Hurricane Research Division (HRD) is a section of the Atlantic Oceanographic and Meteorological Laboratory (AOML) in Miami, Florida, and is the U.S. National Oceanic and Atmospheric Administration's (NOAA) focus for tropical cyclone research. The thirty member division is not a part of the National Hurricane Center but cooperates closely with them in carrying out its annual field program and in transitioning research results into operational tools for hurricane forecasters. HRD was formed from the National Hurricane Research Laboratory in 1984, when it was transferred to AOML and unified with the oceanographic laboratories.
In August, 1992, the AOML/HRD facility sustained moderate damage after the passage of Hurricane Andrew across southern Dade County, Florida, however, despite significant personal disruption to the lives of almost all of its staff members, HRD reconnaissance flights continued into Andrew until it made a final landfall along the Louisiana coastline several days later.
During the 1990s the HRD staff continued to refine its forecasting models, and although a period that included the retirement or transfer of several long-time key research staff members, flew research flights into a number of notable hurricanes of that decade, including Hurricane Opal (1995) and Hurricane Georges (1998).
During the disastrous 2005 Atlantic hurricane season, the HRD staff flew ongoing missions into infamous Hurricane Katrina, which provided invaluable data that continues to be studied at their Miami facility.
Every hurricane season, HRD carries out an annual field program during which it collects information on tropical cyclones (especially Atlantic hurricanes) in order to improve scientific understanding of their formation, structure, and dynamics. Data is collected from satellites, land-based radar, wind towers, and from aircraft. They archive flight information from Air Force Reserve Hurricane Hunters, and plan and participate in research flights on NOAA's Aircraft Operations Center planes. The present fleet consists of two Orion P-3 four-engine turboprops, which can fly directly into the eye of hurricanes, and a Gulfstream IV high-altitude jet, which is used to fly around tropical cyclones, dropping instrument packages called dropsondes.
When not engaged in field operations, HRD scientists and computer programmers process and interpret the information they have gathered. They also work on theoretical studies and produce computer simulations of tropical cyclones and tropical weather. In this work, they collaborate with scientists from many other government and academic institutions from around the globe. The results of their research are presented at conferences and published in the scientific literature.
The National Oceanic and Atmospheric Administration is an American scientific agency within the United States Department of Commerce that focuses on the conditions of the oceans, major waterways, and the atmosphere.
The National Hurricane Center (NHC) is the division of the United States' NOAA/National Weather Service responsible for tracking and predicting tropical weather systems between the Prime Meridian and the 140th meridian west poleward to the 30th parallel north in the northeast Pacific Ocean and the 31st parallel north in the northern Atlantic Ocean. The agency, which is co-located with the Miami branch of the National Weather Service, is situated on the campus of Florida International University in University Park, Florida.
Hurricane 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.

The Atlantic Oceanographic and Meteorological Laboratory (AOML), a federal research laboratory, is part of National Oceanic and Atmospheric Administration's (NOAA) Office of Oceanic and Atmospheric Research (OAR), located in Miami, Florida. AOML's research spans tropical cyclone and hurricanes, coastal ecosystems, oceans and human health, climate studies, global carbon systems, and ocean observations. It is one of seven NOAA Research Laboratories (RLs).
The Atlantic hurricane season is the period in a year when hurricanes usually form in the Atlantic Ocean. Tropical cyclones in the North Atlantic are called hurricanes, tropical storms, or tropical depressions. In addition, there have been several storms over the years that have not been fully tropical and are categorized as subtropical depressions and subtropical storms. Even though subtropical storms and subtropical depressions are not technically as strong as tropical cyclones, the damages can still be devastating.
Christopher William "Chris" Landsea is an American meteorologist, formerly a research meteorologist with the Hurricane Research Division of the Atlantic Oceanographic and Meteorological Laboratory at NOAA, and now the Science and Operations Officer at the National Hurricane Center. He is a member of the American Geophysical Union and the American Meteorological Society.
Robert Homer Simpson was an American meteorologist, hurricane specialist, first director of the National Hurricane Research Project (NHRP) from 1955–1959, 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.
The Atlantic hurricane reanalysis project of the National Oceanic and Atmospheric Administration seeks to correct and add new information about past North Atlantic hurricanes. It was started around 2000 to update HURDAT, the official hurricane database for the Atlantic Basin, which has become outdated since its creation due to various systematic errors introduced into the database over time. This effort has involved reanalyses of ship observations from the International Comprehensive Ocean-Atmosphere Data Set (ICOADS) as well as reanalyses done by other researchers over the years. It has been ongoing as of 2016, and should last another four years.
Tropical cyclone observation has been carried out over the past couple of centuries in various ways. The passage of typhoons, hurricanes, as well as other tropical cyclones have been detected by word of mouth from sailors recently coming to port or by radio transmissions from ships at sea, from sediment deposits in near shore estuaries, to the wiping out of cities near the coastline. Since World War II, advances in technology have included using planes to survey the ocean basins, satellites to monitor the world's oceans from outer space using a variety of methods, radars to monitor their progress near the coastline, and recently the introduction of unmanned aerial vehicles to penetrate storms. Recent studies have concentrated on studying hurricane impacts lying within rocks or near shore lake sediments, which are branches of a new field known as paleotempestology. This article details the various methods employed in the creation of the hurricane database, as well as reconstructions necessary for reanalysis of past storms used in projects such as the Atlantic hurricane reanalysis.
Hurricane Gladys was the farthest tropical cyclone from the United States to be observed by radar in the Atlantic basin since Hurricane Carla in 1961. The seventh named storm and fifth hurricane of the 1975 Atlantic hurricane season, Gladys developed from a tropical wave while several hundred miles southwest of Cape Verde on September 22. Initially, the tropical depression failed to strengthened significantly, but due to warm sea surface temperatures and low wind shear, it became Tropical Storm Gladys by September 24. Despite entering a more unfavorable environment several hundred miles east of the northern Leeward Islands, Gladys became a Category 1 hurricane on the Saffir–Simpson hurricane wind scaleon September 28. Shortly thereafter, the storm reentered an area favorable for strengthening. Eventually, a well-defined eye became visible on satellite imagery.
The National Hurricane Research Laboratory (NHRL) was formed in December 1964 out of the National Hurricane Research Project, the U. S. Weather Bureau's effort to scientifically examine tropical cyclones in order to make better predictions. Laboratory status signified that this effort was now a permanent part of the Weather Bureau's activities.
The Hurricane Weather Research and Forecasting (HWRF) model is a specialized version of the weather research and forecasting model and is used to forecast the track and intensity of tropical cyclones. The model was developed by the National Oceanic and Atmospheric Administration (NOAA), the U.S. Naval Research Laboratory, the University of Rhode Island, and Florida State University. It became operational in 2007.
The Hurricane Databases (HURDAT), managed by the National Hurricane Center, are two separate databases that contain details on tropical cyclones, that have occurred within the Atlantic Ocean and Eastern Pacific Ocean since either 1851 or 1949.

The NOAA Hurricane Hunters are a group of aircraft used for hurricane reconnaissance by the United States National Oceanic and Atmospheric Administration (NOAA). They fly through hurricanes to help forecasters and scientists gather operational and research data. The crews also conduct other research projects including ocean wind studies, winter storm research, thunderstorm research, coastal erosion, and air chemistry flights.
The history of Atlantic tropical cyclone warnings details the progress of tropical cyclone warnings in the north Atlantic Ocean. The first service was set up in the 1870s from Cuba with the work of Father Benito Viñes. After his death, hurricane warning services were assumed by the US Army Signal Corps and United States Weather Bureau over the next few decades, first based in Jamaica and Cuba before shifting to Washington, D.C.. The central office in Washington, which would evolve into the National Meteorological Center and the Weather Prediction Center, assumed the responsibilities by the early 20th century. This responsibility passed to regional hurricane offices in 1935, and the concept of the Atlantic hurricane season was established in order to keep a vigilant lookout for tropical cyclones during certain times of the year. Hurricane advisories issued every six hours by the regional hurricane offices began at this time.
The Hurricane Rainband and Intensity Change Experiment (RAINEX) is a project to improve hurricane intensity forecasting via measuring interactions between rainbands and the eyewalls of tropical cyclones. The experiment was planned for the 2005 Atlantic hurricane season. This coincidence of RAINEX with the 2005 Atlantic hurricane season led to the study and exploration of infamous hurricanes Katrina, Ophelia, and Rita. Where Hurricane Katrina and Hurricane Rita would go on to cause major damage to the US Gulf coast, Hurricane Ophelia provided an interesting contrast to these powerful cyclones as it never developed greater than a category 1.
