Document Summary
0. 0003% is rivers and streams: saline lake: no connection to the ocean, as water evaporates, the salt stays and makes for a very salty lake. Stability and clouds: eventually as the air parcel continues to rise and cool, it may achieve the dew point temperature, saturation, and active condensation. Clouds: cloud: an aggregation of tiny moisture droplets and ice crystals suspended in air with a great enough volume and concentration to be visible, cloud formation processes, collision coalescence process. In war clouds: droplets hit each other and grow: bergeron ice-crystal process. Ice crystals collide and grow: cirrus: air pushing clouds up. Ice crystals: stratus: entire sky covered with grey cloud. Low level: cirrostratus: ice crystals that cover sky, altocumulus: middle level clouds, altostratus: refraction through water vapor. See a halo through clouds: nimbostratus: rain clouds that cover whole sky. Happens with a warm front: cumulonimbus: cumulus cloud for rain.
