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 the temperature to which air must be cooled for water vapor in it to condense into dew or frost. At any temperature there is a maximum amount of water vapor that the air can hold.This maximum amount is called water vapor saturation pressure. Addition of more water vapor results in condensation.ir compression increases water vapor pressure and thus dew point. It is important to take this into consideration if you are bleeding the air to atmosphere before taking a measurement. The dew point at the measurement point will be different from the dew point in the process.
