Term used to denote the major changes that take place in the F-region as a result of solar activity. Ionospheric storms are closely associated with magnetic storms and can lead to severe disruptions of radio-wave propagation, particularly at high latitudes.
Industry:Weather
Term used by World War II pilots to refer to thunderstorms that form regularly over the Tiwi Islands (Melville Island and Bathurst Island) just to the north of Darwin, Australia. The pilots used these storms as navigation aids to return to Darwin after flying sorties.
Industry:Weather
Technique for indirectly determining soil moisture content by measuring the heat capacity of the soil, which varies approximately linearly with water content.
Industry:Weather
Term denoting the system of electrical currents and fields generated in the ionosphere by tidal motions in the background atmosphere. These tidal motions are forced mainly by solar heating of atmospheric water vapor and ozone, and reach large amplitudes at ionospheric heights.
Industry:Weather
Surfaces of constant density. Generally, an isopycnal surface is taken to be a surface of constant potential density, so as to compensate for changes of fluid density caused by varying pressure.
Industry:Weather
Tables that are set up to easily convert the measured dry- and wet-bulb temperatures to common humidity measures like dewpoint temperature or relative humidity. See also psychrometric tables.
Industry:Weather
Study of the the internal structure (i.e., density, temperature, abundance, etc. ) and dynamics (i.e., mixing, rotation rate, etc. ) of the sun from measurements of its surface oscillations.
Industry:Weather
Structures installed in natural or man-made waterways to impound, direct, control, or measure the flow of water. Examples are dams and spillways, sluice gates, weirs, and flumes.
Industry:Weather
Strictly, a fluid with uniform properties throughout, but meteorologists sometimes designate as homogeneous a fluid with constant density. No fluid is homogeneous in an absolute sense. Homogeneity must be specified relative to a characteristic length (e.g., the size of the probe used to measure the properties of the fluid). Compare heterogeneous fluid.
