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 closely linked to relative humidity, which is the ratio of the pressure of water vapor in a parcel of air relative to the saturation pressure of water vapor in that same parcel of air at a specific temperature. Relative humidity (RH) is expressed as a percentage.ompared to relative humidity, dew point is frequently cited as a more accurate way of measuring the humidity and comfort of the air, since it is an absolute measurement (unlike relative humidity). Most people are comfortable with a dew-point temperature of 60 degrees Fahrenheit (16 degrees Celsius) or lower.
