Term | Definition |

Heat budget | The balance between energy input and energy output from the sun. |
Upwelling | Warm, less-dense surface water is drawn away from along a shore by offshore currents and replaced by cold, denser water brought up from below. |
Coriolis Effect | A deflection or apparent veering motion of air masses as they move or deflect from one latitude to the next. |
El NiƱo | Climatic phenomenon known for low fish populations, more severe hurricanes and droughts in agricultural areas. |
Prevailing Westerlies | Wind patterns found between 30 and 60 degrees latitude. |
OTEC | Ocean Thermal Energy Conversion is a process or technology for producing energy by harnessing the temperature differences (thermal gradients) between ocean surface waters and deep ocean waters. |
Hurricane | Cyclones that form at low pressure cells have winds up to 200 m/h. |
Trade Winds | Strongest wind belts found between the equator and 30 degrees latitude. |
Pack Ice | Sea surface ice that does not form over land. |
Thermohaline circulation | Part of the large-scale ocean circulation that is driven by global density gradients created by surface heat and salinity. |
Kyoto Protocol | An agreement among 60 nations to voluntarily limit greenhouse gas emissions. |
Cold Front | A cold air mass moving into an area occupied by relatively warm air. |
Horse Latitudes | Weak surface wind at 30 degrees latitude. |
Occluded Front | Very swift cold front takes over slower warm front causing conditions favorable for thunder storms, tornadoes, etc. |
Monsoon | Wind circulation that changes with the seasons. |
Gyre | Water current pattern formed by surface winds, sun's heat energy, gravity, and Coriolis effect. |
Doldrum | Weak winds at 0 degrees (equator). |
ENSO | El Nino and Southern Oscillation combined whose effects can last more than 3 years. |
Polar Easterlies | Wind pattern found at poles above 60 degrees latitude. |
Maritime | Pertaining to the ocean. |
