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).
Dew point is a measure of atmospheric moisture. It is the temperature to which air must be cooled to reach saturation (assuming air pressure and moisture content are constant). A higher dew point indicates more moisture present in the air. high relative humidity implies that the dew point is closer to the current air temperature. Relative humidity of 100% indicates the dew point is equal to the current temperature and that the air is maximally saturated with water.
