Document Summary

Introduction: climate vs. weather, weather -> day to day, climate: long term avg. 2. 6 p. 52) based on long term temperatures and precipitation conditions. Pacific: marine influence of pacific ocean, moderate temperatures - warm summers. Arctic: seasonal variation in precipitation -> wetter in winter, orographic precipitation, windward side of the mountains more precipitation, higher elevation -> lower temperatures, different climate regimes as different elevations, amount of precipitation varies from windward to leeward locations. Latitude -> colder temperatures: resolute -> mean annual temp. Subarctic (see vignette 2. 9 p. 56: cold winters (but avg. temp. > arctic region: 5 months with avg. temp. > 0 c (may- sept. : high range in winter to summer temps, continental climate - hot summers, cold winters, area over which polar/ tropical are masses meet; some parts very arid, e. g. prairies. Great lakes: humid continental climate, restricted to southern ontario/ quebec, moderating effects of great lakes, hot/ humid summers; cold winters, 8 months with avg. temp.

if the ocean climate were no changing, the heat fluxes into and out of the ocean would be equal. let's suppose that these fluxes are slightly out of balance and that of the 342 W/m^2 (1Watt= 1Joule/s) that reaches the upper atmosphere 4 W/m^2 contributes to warming the oceans. if a heat flux of 4 W/m^2 covered the 3.75x10^16 m^2 ocean surface and contributed only to a change in temperature, how many years would it take to raise the average temperature of the oceans 2 degrees C
