  2. Introduction • The different biomes of the world are characterized by different vegetation • Walter Climate Diagrams relate annual precipitation and temperature • The type of vegetation can be inferred from a Walter Climate Diagram

  3. Objective • To compile temperature and precipitation data over the past 16 years in Morro do Diabo and relate these two variables in a Walter Climate Diagram.

  4. Methods • Weather records were collected from the Morro do Diabo State Park, Sao Paolo, Brazil • From the available data (1977-1996), four Walter climate diagrams were constructed • A four year interval was omitted (lack of data)

  9. Observations • There are periods of times within the year (july-august) that receive considerably less rainfall. • This abiotic factor acting synergistically with the annual decrease in temperature (tropical winter) may account for the deciduous habit expresses by some trees within the region

  10. Results • Annual rainfall for Morro do Diabo State Park > 1300mm for the time intervals studied • February and March were consistently the months of highest temperatures • July and August were consistently the months of lowest temperatures • the average annual temperature ranged between 22.5 and 22.7 oC

  11. Conclusion • After examining the World Climate software and analyzing data specific to this site, we have classified this ecosystem as a mesophytic deciduous rainforest, part of the larger Moist Atlantic Rainforest, typical of South East Brazil.
