Document Summary
Based on the thornthwaite approach to rational classification of climate. What are the two most widely measured climatic variables on earth: temperature and precipitation. Uses temperature & precipitation as inputs for the creation of water balance for a site. Evapotranspiration is the output, calculated from temperature. Here, we are looking at changing temperature to create an energy term. Incorporates soil water storage, depletion & recharge: look at the summer months here; it"s obvious it"s in the northern hemisphere. More consistent p close to large body of water. Accumulated water loss only calculated only for negative p-pe. The less water there is in the soil, the harder it is to take out: if you have acc wl at end of year that crosses over to next year, calculations should still be accumulated. Soil water storage based on acc wl. Actual evapotranspiration: any month with a change in storage, you should have p
