the lowest layer of earth's atmosphere, where weather occurs
the layer of the atmosphere that contains the ozone layer; temperature increases as you go up
the layer of the atmosphere between the stratosphere and the thermosphere and in which temperature decreases as altitude increases.
The uppermost layer of the atmosphere, in which temperature increases as altitude increases
process by which atmospheric gases trap heat close to Earth's surface and prevent it from escaping into space
the percentage of water vapor in the air compared to the maximum amount of water vapor that air can contain at a particular temperature
temperature at which air is saturated and condensation forms
A puffy, fair weather cloud with a flat bottom and "heaped up" top.
Clouds that form in low, horizontal layers, cover all or most of sky
the result of the weight of a column of air pushing down on an area
an instrument used to measure atmospheric pressure
an instrument used to measure wind speed
an instrument for measuring humidity
causes moving air and water to turn left in the southern hemisphere and turn right in the northern hemisphere due to earth's rotation
Prevailing winds that blow northeast from 30 degrees north latitude to the equator and that blow southeast from 30 degrees south latitude to the equator
Prevailing winds that blow from west to east between 30 degrees and 60 degrees latitude in both hemispheres
a body of air that has about the same temperature and moisture throughout
a front where warm air moves over cold air and brings drizzly rain and then is followed by warm and clear weather
forms when cold air moves under warm air which is less dense and pushes air up (produces thunderstorms heavy rain or snow
a front where a warm air mass is caught between two colder air masses and brings cool temperatures and large amounts of rain and snow
incoming solar radiation
Earth's position around June 21, at which the northern hemisphere has its maximum daylight hours
Earth's position near or on December 21, at which the northern hemisphere has its minimum daylight hours
occurs in March when the sun is directly overheat at the equator and results in day and night of equal length for both hemispheres
occurs in September when the sun is directly overheat at the equator and results in day and night of equal length for both hemispheres
an irregularly occurring and complex series of climatic changes affecting the equatorial Pacific region and beyond every few years, characterized by the appearance of unusually warm, nutrient-poor water off northern Peru and Ecuador, typically in late December.
A local wind that blows from an ocean or lake
movement of air from land to sea at night
A type of cumulus cloud that is tall and gray, and associated with thunderstorms.
warm air and cold air masses push into each other but neither move; causes light wind, clouds, rain that can last for several days; represented on a weather map by blue triangles and red semicircles
continental tropical air mass
hot, dry air mass that forms over land
continental polar air mass
cold, dry air mass that forms over land
maritime tropical air mass
Humid, warm air that brings in moisture from the sea.
maritime polar air mass
Cold, moist air mass that forms over the ocean
The average weather conditions in an area over a long period of time
Gases such as carbon dioxide, methane, nitrous oxide, water vapor, and ozone in the atmosphere which are involved in the greenhouse effect.
