Ch 25 & Ch 21 - Oceans & Climate
The average weather conditions for an area over a long period of time
A scientist that studies climates
occurs every 3-10 years when surface-water temperatures along the west coast of South America rise which changes global weather patterns
GENERAL CIRCULATION MODEL
used to simulate changes in a variable using climate data and computers
The gradual increase in average global temperatures due to higher concentrations of gases such as carbon dioxide
used to measure concentrations of gases and ice in meltwater and can give clues about atmospheric conditions from hundreds of thousands of years
a cool-water phase that also affects global weather patterns
a combination of factors dealing with Earth's orbital changes and how they can change the global climate
A seasonal wind that blow toward the land in summer and away from the land in winter
when an air mass encounters a mountain range and it rises, cools, and loses its moisture as precipitation creating a warm dry climate on the other side of the mountain
The quantity of heat required to raise a unit of mass of a substance by 1 K or 1oC
exist between 20 - 30 degrees latitude in both hemispheres and the air sinks, warms, and dries
YEARLY TEMPERATURE RANGE
The difference between the highest and lowest monthly averages
An area of warm temperatures from 23.5oN - 23.5oS latitude
An area of seasonal change from 23.5o - 66.5o N & S latitude
A region of cold air from 66.5o - 90o N & S latitude
A horizontal movement of water in a well defined pattern
A horizontal movement of ocean water that is caused by wind that occurs at or near the ocean's surface.
The apparent curving of the path of a moving object from an otherwise straight path due to Earth's rotation.
A huge circle of moving ocean water found above and below the equator.
The swift, deep, and warm Atlantic current that flows along the eastern coast of the United States toward the North.
A slow moving stream-like movement of cold and dense ocean water far below the surface.
Ocean currents that are affected by the presence of a coastline.
A strong channel of water flowing from the coast toward the ocean.
The large scale ocean circulation that is driven by density differences created by the heating of surface water.
