QuestionAnswer
Cyclone low pressure system types, such as tropical cyclones, extra tropical cyclones and tornadoes. ... AKA hurricanes and typhoons.
How do cyclones rotate? counterClockwise
Anticyclone a large-scale circulation of winds around a central region of high atmospheric pressure, clockwise
What happens during a cyclone? They usually dissipate over land or colder oceans.
What conditions Cyclone form? Tropical cyclones are like giant engines that use warm, moist air as fuel, form over warm ocean waters near the equator.
Wind is air in motion, movement of air
how does wind form? the sun heats one part of the atmosphere differently than another part= expansion of warmer air, less pressure where warm than where it is cooler.
wind direction is determinded by where is originates/comes from
Cloud a visible mass of condensed water vapor floating in the atmosphere, typically high above the ground.
High cloud - cirrus, cirrocumulus, cirrostratus.
Middle cloud altostratus, altocumulus, nimbostratus.
Low Cloud stratus, stratocumulus.
Vertical cumulus, cumulonimbus.
What are Clouds made of? Clouds are made up of tiny droplets or frozen crystals of water.
How do clouds form? as warm air rises in the atmosphere and cools down.
High form above 20,000 feet.
middle form between 6,500 and 20,000 feet high
low form below 6,500 feet.
Vertical very tall and may span many of the cloud levels. Vertical clouds usually have the word "cumulus" in their name.
cloud formation As warm air cools the water vapor turns into tiny droplets of water or ice. As more and more air cools down, more droplets form and they eventually become a cloud.
Cirrus high level clouds that are thin and wispy; appear during good weather.
Cirrocumulus high clouds that look like tiny cotton balls bunched together.
Cirrostratus High, flat clouds that might cover the sky making it appear overcast; signal that it may rain in the next day or so
Altostratus Medium level clouds that form a dark gray covering; Usually a sign of rain.
Altocumulus - Middle level clouds that are small, white, and puffy.
Nimbostratus thick, dark gray middle level to low level clouds; usually bring rain or snow.
Stratus low level clouds that are flat and tend to cover much of the sky; may produce light rain or drizzle.
Stratocumulus low, puffy, and gray clouds; may produce a little rain
Cumulus low to mid-level clouds; big, white, puffy, and beautiful.
Cumulonimbus tall clouds that span all the way from low level to high level
A cloud that forms on the ground is called Fog
Some clouds you see in the sky might be from airplanes. These are called Contrails
High level cirrus clouds may travel at speeds up to 100 mph
Even though clouds float in the air, a single cumulus cloud can weigh hundreds of tons
Other planets with atmospheres have clouds including Venus, Jupiter and Saturn
Barometer measures pressure
Isobars lines of equal pressure
Types of Precipitation rain, snow, sleet, or hail that falls to the ground.
Coriolis Effect Apparent deflection of wind currents from ocean due to earths rotation
RACE-C stands for Rising air cooling expanding condenses
hurricane winds turning left in the Northern hemisphere. An example of the Coriolis effect
How sea breeze forms during the day RACE-C
How is wind named? Direction comes from
What causes wind? Hot air rises and cold air sinks
Closer the isobars Higher wind speeds
Cloud formation ingredients Water vapor, air to cools dew point, condenses tine particles
Temp equals dew point is at Clouds flat bases
Stationary front Cold air and warm air don't move
Occluded front Cold front overtakes slow moving, warmer air
warm dense air rises-Higher altitude low pressure
cold, denser air sinks-Lower Altitude high pressure
Cyclone air inward moving air and up so it converging
Anticyclone air outward moving and downward so it diverging
Cloudy Cyclone
Meteorology Study of the atmosphere including weather
Weather condition of the atmosphere ( ranges based on time and place)
move at the speed of light electromagnetic waves
dark surface absorbs more energy, hotter
light surface reflects more energy, cooler
rough surface area more surface area absorbs
smooth surface area less surface area reflects
shorter wavelength greater frequency=more energy
larger wavelength lower frequency=more energy
energy travel high to low
energy stops transferring when becomes equal
measure how fast molecules move Temperature
faster particles hotter
anticyclone not cloudy
Thermometer measures heat
Psychrometer measures dew point and humidity
Anemometer measures wind speed
Rain Gauge measures rainfall
Weather Vane measures direction
