Hurricane Research Division

Hurricane Research Division is a earth science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Hurricane Research Division rather than just read about it. In short: 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.

Key takeaways

Hurricane Research Division belongs to earth science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Hurricane Research Division to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Hurricane Research Division from memory before moving on to harder problems.

Reference excerpt

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.

Worked examples

Example 1 — a first encounter with Hurricane Research Division

Start with the simplest possible case. Write down what Hurricane Research Division claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In earth science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Hurricane Research Division before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Hurricane Research Division ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Hurricane Research Division

In research: Hurricane Research Division appears in earth science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Hurricane Research Division in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Hurricane Research Division is common in secondary-school and first-year university syllabi. It links to neighbouring topics National Oceanic and Atmospheric Administration, so understanding it makes those chapters shorter.
In everyday life: Look for Hurricane Research Division outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
