Scientists make deductions about how the world works by proposing hypotheses and testing them against available data. The best hypothesis is one which is simple, is consistent with available data and our knowledge of how other things work, and makes predictions which can be tested against new data.
Below are several hypotheses which seek to explain the gross features of the diurnal temperature cycle: the times of the max and min and the rates at which temperature rises and falls. Read the hypotheses, then click on the link of the hypothesis which you feel is both simple and consistent with the available data. You will then test your hypothesis by examining additional data. If the hypothesis turns out to be inadequate, you will come back to this page and select a different hypothesis.
- Hypothesis One: The temperature is proportional to the solar radiation.
- Hypothesis Two: The temperature change is proportional to the solar radiation.
- Hypothesis Three: The temperature change is proportional to the solar radiation minus some constant energy loss.
- Hypothesis Four: The temperature change is proportional to the solar radiation minus some random energy loss which is a function of time.
- Hypothesis Five: The temperature change is proportional to the solar radiation minus an energy loss which is a function of the temperature.
- Hypothesis Six: The temperature change is caused by the advection of warmer or colder air into the area.
