Subject: F8) How is storm surge observed and measured?
Contributed by the NHC Storm Surge Unit
There are several methods used by NOAA, the United States Geological Survey (USGS), and the Federal Emergency Management Agency (FEMA) to measure storm surge. Each method has advantages and draw backs and post-storm analysis of storm surge requires resolving differences in what each measures to find the best approximation of the surge heights.
- Tide Stations (NOAA)
A network of 175 long-term, continuously operating water level stations located throughout the U.S. serving as the foundation for NOAA's tide prediction products.
- Measures still water (e.g. no waves)
- Traditionally the most reliable method
- Limited, fixed stations
- High Water Marks (USGS / FEMA)
These are the lines left on trees and structures marking the highest (peak) elevation of the water surface from a flood event. They are created by foam, seeds, and other debris. Survey crews deploy after a storm, locate, and record reliable high water marks. GPS methods are used to determine the location of these marks, which are then mapped relative to a vertical reference datum.
- Perishable
- Traditionally best method for capturing highest surge level
- Subjective and often includes impact of waves
- Pressure Sensors (USGS)
These are temporary water-level and barometric-pressure sensors which provide information about storm surge duration, times of surge arrival and retreat, and maximum depths.
- Relatively new method
- Mobile, deployed in advance of storms at expected location of highest surge
- Can contain impact of waves

How does heat in the atmosphere move?
An alternate term for A Low Pressure System is literally a vast heat transfer pump; taking tropical heat to the Arctic and arctic cold South.
How many people died in hurricane igor?
Scientists and meteorologists have no clear cut cumulative number of deaths that have occurred over the history of man on Earth. Taking the fact that the costliest tropical cyclone, Bhola 1970, killed as many as 500,000 people, we can probably say that hurricanes have killed, in the span of hundreds of thousands of years, over at least 100 million people.
What are the advantages and disadvantages of cyclones?
disadvantages - 1. it causes large scale destruction to people, life and property. 2. it can bring diseases 3. It causes flooding 4. It destroys the habitat of many species of animals 5. Agriculture is greatly affected by torrential rain brought by cyclones Advantages: 1. It brings lots of rainfall to a country's reservoir 2. It cleanses the atmosphere 3. It removes many branches on tall trees and allows sunlight to reach young plants 4. It irrigates the fields 5. It can also eradicate a previous disease present in the air
What instruments are used to measure tornadoes?
Today, tornadoes, thunderstorms and other, related weather are being tracked by a system called the Doppler Radar. The Doppler Radar contains a visible screen, which contains the tracked map of the area. Areas in deep reds and purples, which represents heavy rain, depicts severe thunderstorms. If those colours form into a hook, a tornado or funnel cloud is likely. Doppler radar can also measure the relative wind speeds withing a storm. An area of strong winds moving toward and away from the radar in a small area indicates strong rotation that may lead to a tornado.
Why does much of the continental US have a large number of storms?
wrong answer - very little heat is transferred here as the cold and warm air masses intermix freely sorry... that's all i know right now... still taking the test. This is Jennifer i got the right answer.....------ Because the polar and tropical air masses meet in conflict there. I am positive that is the right answer.. so don't get me wrong. Okay. :)
What is the main instrument for taking measurements of a tropical cyclone out at sea?
SATELLITE

yes
How you change the face for taking angle in theodolite?
A theodolite is an instrument that is used in archaeoastronomy. To change the face for taking angle measurements when using a theodolite you must turn the telescope by 180 degrees.
What is an negative sight in surveying?
A negative sight in surveying occurs when the vertical line of sight from the instrument to the target is below the instrument's horizontal axis. This can result in incorrect measurements and lead to inaccuracies in the survey data. Negative sights should be avoided by ensuring that the instrument is properly leveled before taking measurements.
What are some guidelines for obtaining accurate observations?
