But when the outdoor temperature is around zero degrees and I keep the thermostat at 68, I have to bundle up like an Eskimo inside. Why? It has to do with the relative humidity. A higher indoor relative humidity makes the 68 degree.
Prescribed fire treatments are always dependent on conditions such as wind.
This seemingly indicates that more (less) heat is needed for an open ocean to maintain an air mass above it with a same degree of temperature rise during a colder (warmer) season [or in a colder (warmer) region]. Q and SST are also found to be positively correlated. Relative humidity (RH) exhibits similar behaviors for.

Feb 11, 2014. The dew point is the temperature at which air is saturated with water vapor, which is the gaseous state of water. When air has reached the dew-point temperature at a particular pressure, the water vapor in the air is in equilibrium with liquid water, meaning water vapor is condensing at the same rate at which.
