Standard Atmosphere - Hypothetical vertical profile of the atmosphere that was developed to represent the time and horizontally averaged distribution of temperature, pressure, and density. In the standard atmosphere, pressure, density and temperature are a function of height only. The standard atmosphere is used internationally to standardize calibrations and measurements. In a standing wave in a fluid, parcel motion may flow through the wave without movement of the wave structure itself. Atmospheric planetary waves are generally standing waves because the orography forcing the wave is stationary.
Stratocumulus clouds can result when layers of clouds are heated from below and convection follows.
Stratocumulus clouds, one of four genera that are hybrids of cumulus clouds, are made up of water drops and possibly hail and snow. They are very common over portions of the world's oceans and are thought to be very important in determining the Earth's radiation budget. The top of the stratosphere, where the transition occurs between the stratosphere and the mesosphere above it. The stratopause is located at a height of about 50 kilometers. The atmospheric region that lies above the tropopause.
