Water Cycle
The process in which water pools in large bodies of water.
Air pressure changes with what?
Altitude!!
How is wind created?
Wind forms when air flows from high to low pressure. Winds are described by their origin and speed. Many different wind patterns.
What is El Nino?
Unusually warm, nutrient-poor water off northern Peru and Ecuador, typically in late December.
What are the five parts of the water cycle?
Condensation
Precipitation
Runoff
Evaporation
Transpiration
Explain what precipitation is.
Water falling to the Earth in the form of weather.
Tell me 3 characteristics that show low pressure.
Less dense, warmer, and high altitude
Which direction does wind blow?
West to east in the northern hemisphere (depends on sun and Earth’s rotation)
What is La Nina?
A cooling of the water in the equatorial Pacific, which occurs at irregular intervals, and is associated with widespread changes in weather patterns complementary to those of El Niño, but less extensive and damaging in their effects.
How do clouds form?
Form when water vapor in air condenses
Explain what condensation is.
Water vapor molecules join together becoming liquid (in the form of clouds).
Tell me 3 characteristics that show high pressure.
Denser, colder, low altitude
Describe the wind patterns at the poles.
They're slower and circling the poles.
What is a stationary front?
When two air masses come together but neither displaces the other, the boundary between them is referred to as a stationary front. It is difficult for meteorologists to predict the weather along a stationary front, though it often resembles that of a warm front.
What is a cold front?
A cold front is a boundary between two air masses, one cold and the other warm, moving so that the colder air replaces the warmer air.
What is dew point? What happens above and below freezing?
The temperature at which condensation begins (above freezing- water droplets form, below freezing- ice crystals form).
....Miss Loflin, show us the picture...
Higher altitude, less air pressure
What is the Coriolis Effect?
Due to impact of Earth's rotation on its own axis, the winds move slightly to the right in the northern hemisphere and to the left in the southern hemisphere . this effect is called Coriolis effect .the most important effect of Coriolis force is the deflection of winds and current in the ocean.
What is an occluded front?
Occurs when a cold air mass takes over a warm air mass.
How is weather predicted?
Weather forecasting involves a combination of computer models, observations, and a knowledge of trends and patterns.
What 3 factors affect cloud formation?
Clouds need a nuclei, water vapor, and low pressure to form.
Explain what happened in the Stubborn Balloon. Where did air pressure change? Did the balloon get pushed or pulled in?
Freezer:
Warm Water:
Explain the wind pattern- jet streams.
A jet stream is a band of fast-moving wind that is high up in the atmosphere. Jet streams form at the boundaries between hot and cold air masses and tend to be westerly, which means they blow from the west to the east.
What is a warm front?
Fronts that bring warm air are referred to as warm fronts. As this warm air approaches, it is lifted upward above the cooler air. As the air in the warm air mass rises it expands, causing it to cool down. As it cools, water vapor can condense, creating precipitation.
Explain evaporation.
The process by which liquid turns into water vapor when heated by the sun.
