A condition caused by the decrease in atmospheric pressure over the Eastern Pacific Ocean, weakening the prevailing westerly winds and resulting in warm waters and less nutrient replacement from cold, deeper waters into the Eastern Pacific along the coast of South America. This event creates strange weather patterns worldwide sometimes causing flooding in California and droughts in South America simultaneously. The effect gets it name from the Spanish for the Christ Child--the little one--because it is experienced in December by the local fisherman off the western coast of South America as a poor fishing season.
Industry:Chemistry; Weather
A consistent change in the sea level that affect oceans, throughout the world.
Industry:Chemistry; Weather
A dark area, which is strongly magnetic, that occurs in the area of the photosphere on the disk of the sun.
Industry:Chemistry; Weather
A device that reduces pollution from smokestacks. It gives the particles in smoke an electrical charge. The charged particles are then collected on filters that have the opposite charge and the particles are thereby removed from the emission stream.
Industry:Chemistry; Weather
A diagram that presents information about wind speed and direction for a particular area over a certain amount of time. The diagram is a circle with spokes. The center is 0 and as the wind frequency increases bars extend from the center of the circle to the outside of the circle, in the direction the wind is blowing. Direction can be determined by which way the bar is extending to the outside of the circle because the wind rose is set up like a compass. Information for a windrose is gathered by monitoring stations throughout the area being monitored. By determining wind speed, direction, and frequency with a wind rose, movement of air, and pollutants can be predicted.

A dispersion of solid particles is a liquid system.

A family of chemical compounds formed by the addition of chlorine to a biphenyl system (a dual-ring structure comprising two benzene rings linked by a single carbon-carbon bond). They are categorized as a TOMP (Toxic Organic Micro Pollutant). PCBs are released into the atmosphere through the incomplete combustion of fuel or the processing of old electrical transformers or capacitors and are particularly long-lived, with atmospheric destruction of PCBs usually caused by reaction with OH radicals. The ultraviolet wavelengths that destroy PCBs do not make it to the troposphere because they are blocked by the ozone layer, but photolysis can occur in the upper atmosphere. Bioprocessing by organisms in soil and water is a much more common, though very slow destruction route for PCBs. PCBs have been found in some organism on all the earth's continents.
Industry:Chemistry; Weather
A fictional source associated with the earth's rotation. It results in the deflection of all objects not at the equator to the right in the direction of motion in the northern hemisphere and to the left in the southern hemisphere.
Industry:Chemistry; Weather
A function of the diameter and number of particles; used to study particulate matter in the atmosphere and to determine atmospheric concentrations. SA &#61; (pi)D<sup>2</sup>, where D is the diameter of a particle.
Industry:Chemistry; Weather
A given material’s ability to conduct heat energy. The process of conduction means that heat energy will flow through the material without the material moving to carry it. The heat energy inside the material will naturally flow to the area with the lowest temperature. Air has different thermal conductivity values at different temperatures. The ability of atmospheric air to house different thermal conductivities make it one of the many factors that influence the weather.
