Was in the canope and discovered there are many epiphites. (air plants). They use other plants for structure support.
Input omes from sun, electromagnetic radiation. 30% of energy gets reflected back into space (albeto). Snow can reflex 90% of albeto, asphalt has a low albeto. 70% of radiation striking earth is absorbed into the earth.
What happens to the absorbed energy?
Photosythenthisis absorbs a tiny amount.
Most is absorbed as heat.
- Heat must dissapate to E inputReradiated at nightConverted to windInvlovled in evaporationAll leaves eventually in the form of
- terrestrial longwave radiation (heat)
Hemispheres and seasons-
Northern hemisphere has spring equinox an equator faces the sun. Southern hemisphere has autumn equinox
June 21st is the longest day of the year. The sun will be directly over the tropic of cancern.
Sept 21st sun will be over the equator, equal day and night, Shortest day in the northern hemisphere, longest in the southern hemisphere.
During the winter, we are closer to the sun although we are tilted away so that it is colder.
While the heat is being converted from one form to another it takes on enrgy that drive climateAtmospheric circulation
30 degrees on the globe there are
deserts. Called inter-tropical convergence. ITC is the major climatic heat engine of the planet. The closer you are to the equator the faster you are moving
Coriolis effect due to earth’s spin
- Breaks up air circulation and produces trade
due to air current, absorbed energy by water, strongly influenced by continental positions, coriolis effect (earths spin)
- -Atmosphere circulation
- -Ocean currents
- -Topography- pronounced effect on local climate
- Coastal deserts-cold ocean currents
- Eastern vs. western Oregon
- Amazon basin
Temperature and preciptaion
are critical compontents of climate
Temperature controls the duration
Precipitation = supply
Humidity = demand
Precipitationshadow (rain shadows)
