| Question | Answer |
|---|---|
| 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 |
