Document Summary
If atmosphere is cold, there is moisture that is soaked in the shirt cold atmosphere tends to be drier, specific humidity is lower that saturation specific humidity tendency for clothes to release latent heat to the atmosphere. Temperature increases and holds more moisture and dew point increases; humidity will be much less than the amount the room can hold and thus relative humidity will be falling. Saturated (salr: rate of temperature decrease with altitude for a parcel of air that is saturated with water vapour as it rises: 4-9 c/1000m, condensation is happening and it rises and latent heat is released. What is atmospheric stability: occurs when air parcel is at equilibrium with its surroundings, no vertical movement occurs, stability: air parcel resists upward displacement. Summertime because the temperature at the surface is usually high and the as air rises, it will have lower density and be more buoyant thus will continue to rise to higher altitudes.
