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).
Definition. The dew point is the temperature at which moisture condenses out of the air. It is related to the humidity ratio -- the mass of water that is present per mass of dry air. The drier the air is, the lower the dew point temperature will be.For example, a dew point temperature below freezing indicates very dry air.tep 2: Vapor Pressure. Relative humidity can be expressed as a ratio of the saturation vapor pressure at the dew point temperature to the saturation vapor pressure at the air temperature. This is expressed by the formula RH = 100*(e/e s).
