What tools did the people use to find out that there is going to be a hurricane?
Wind speed, humidity, barometric pressure, satellite maps, radar maps, predictive weather models.
How do they measure the severity of hurricanes?
they measure hurricanes on the saffir-simpson scale ( category 1,2,3,4,5) by measuring the following 4 things: barometric pressure, wind speed, storm surge, and possible damage.
How does the boiling point of a liquid vary with pressure?
Something boils when its vapor pressure equals the atmospheric (barometric) pressure above it. When the two are equal, that defines the boiling point.Therefore, you can either boil something by heating the liquid, and thus raising its vapor pressure (vapor pressure goes up with temperature), or you can boil something by reducing the atmospheric pressure above it until it matches the vapor pressure.See the Related Questions links to the left for more information about how the boiling point of water changes with elevation and atmospheric pressure.
How do pressure differences effect wind speed?
Diverging wind helps evacuate air from a region, thus lowering its pressure. However, diverging wind at the surface is associated with high pressure, because air is converging aloft and subsiding, whereupon it reaches the surface and spreads out.
How are fluid speed and fluid pressure related?
As the speed of a fluid increases, the pressure within the fluid decreases.
Where do meteorologists get there barometric pressure data?
from the barometer it measures wind speed
Who decides hurricane or tropical storm?
The category of the storm - depends on the wind speed, and barometric pressure reading.
How are the spacing of isobars and wind speed related?
Distribution of isobars on a map is connected with the direction and speed of the wind. As the isobars grow closer together it shows a rapid change in barometric pressure, which can indicate a storm front approaching - and that usually means increased winds.
What does meterological data mean?
Meteorological data is information obtained from the atmosphere, Such as; barometric pressure, humidity, wind speed, and air temperature.
What is the effect of pressure and speed in sound waves?
Speed affects the frequency and pressure affects the wavelength.
Would it be correct to say that the Doppler effect is the apparent change in the speed of a wave due to the motion of the source?
No. The Doppler effect is about a change of frequency, not about a change of speed. The relative speed may change as well, but that's not what the Doppler effect is about.
What has a bigger effect on wind speed temperature or air pressure?
The bigger affect on wind speed is air pressure.
Is Katrina the strongest storm?
No. It was the most destructive, but by no means the strongest. Other storms have been stronger in terms of both wind speed and barometric pressure.
Does the wave speed change in the Doppler effect?
Yes, the Doppler effect defines the change in speed of a sound wave due to motion. As I recall, the Doppler Effect is a change in the frequency of a wave, not its speed. Yep, I'm pretty sure Doppler is a frequency change, not a speed of sound change.
What tools did the people use to find out that there is going to be a hurricane?
Wind speed, humidity, barometric pressure, satellite maps, radar maps, predictive weather models.
What does high pressure do to sound?
The speed of sound does not change with atmospheric pressure. The speed of sound changes with temperature.
How does meter contribute to the meaning of a word containing that word part?
'Meter' means to measure, so to add it to another word is to use it to state a measurement of the other word. For example: Thermometer - thermo, meaning heat, so it measures the temperature Speedometer - speed, meaning how fast, so it measures the speed of movement Barometer - baro, meaning barometric pressure, so it measures the barometric pressure
