They often grow alongside Black Cherry, American Beech, American Hornbeam, Eastern Red Cedar, as well as others. Sassafras is allelopathic to some plants, such as American Elm. This means it releases a chemical which keeps these plants from growing well.This allows Sassafras to grow better, without so much competition. Sassafras flowers are greenish-yellow, and grow in clusters.hey often grow alongside Black Cherry, American Beech, American Hornbeam, Eastern Red Cedar, as well as others.

Dew point depression. The dew point depression (T-Td) is the difference between the temperature and dew point temperature at a certain height in the atmosphere. For a constant temperature, the smaller the difference, the more moisture there is, and the higher the relative humidity. In the lower troposphere, more moisture (small dew point depression) results in lower cloud bases and lifted condensation levels (LCL).
Dewpoint is the temperature where condensation begins, or where the relative humidity would be 100% if the air was cooled. This is readily apparent from the diagram for water vapor, given that dewpoint is just a more intelligible way to express partial water vapor pressure (see Figure 2: Dewpoint of gas at 42% RH).
