Weather |
A set of environmental conditions seen day to day (ex: temperature, POP, wind, humidity) |
|
|
Climate |
The average of the weather in the region over a long period of time. |
|
|
The world is divided into 5 major climate zones |
Tropical, moist climate - all months average about 18C, annual precipation greater than 1500mm Dry climate- temp range from 40C - -40C, low precipation exceeded by evaporation Moist, mid-latitude climate with mild winters- warm to hot summers, no colder than -3C on average Moist, mid-latitude climate with cold winters- warm to cool summers, average below -3C in colder months Polar Climate- cool summers and extremely cold winters |
5 major climate zones based on: average monthly temperature and precipitation and average annual temperature and prepcipation |
|
Factors affecting climate |
Latitude, ocean currents, winds (jet streams), elevation, landforms, nearness to water |
L.O.W.E.R |
|
La Niña |
a cooling of the water in the equatorial Pacific that 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 |
|
|
Feedback loop |
A process in which the result acts to influence the original process |
|
|
Albedo |
The amount of radiation that a surface reflects |
Examples: grass has a low albedo and ice has a high albedo |
|
Evidence of climate change |
Global warming, changes in polar and glacial ice, ocean acidity has decreased, climate/ health, change in wind patterns, change in precipitation patterns, storm intensity and frequency, changing biomes |
|
|
Spheres and definitions |
Hydrosphere- all of the water on the earth Atmosphere- the air around the planet Biosphere- all living things on the planet Lithosphere- all of the land on earth |
Harry's L.A.B |
|
The different layers of atmosphere |
Mesosphere( meteors that enter earth's atmosphere burn up here) Stratosphere( contains ozone layer) troposphere(contains people and weather) exosphere(outer space contains human made stallions in orbit) thermosphere(a very hot layer, many chemical reactions occur easily here) |

|
Sink |
A process that removes green gases from the atmosphere |
|
|
Source |
The source of greenhouse gases puts the gases into Atmosphere. A source can be natural, anthropogenic or both |
Example human emissions (cars, factories) |
|
Anthropogenic |
Resulting from human influence |
|
|
Greenhouse gases |
Water vapour (doesn't effect atmosphere), methane (CH3), carbon dioxide (CO2), ozone (O3), nitrous oxide (N2O), CFCS (Chlorofluorocarbons) |
women crush men on new clean floors |
|
Thermohaline circulation |
A 3D pattern of ocean circulation driven by wind, heat and salinity |
|
|
Global warming may disrupt the current pattern resulting in... |
1. Melting ice- increase fresh water- lowers salinity in northern oceans (becoming less dense) northern waters will travel toward the equator and vice versa resulting in melting ice 2. Evaporation rate increases- increases salinity in tropical oceans (becomes more dense) |
|
|
El Niño |
A recurring change in the pacific winded and ocean currents that brings warm, moist air to the west coast of South America. |
