Yellowstone Fires
When moisture-laden warm air is heated, it begins to rise. Air, like water, moving in one direction is called a "current." As warm, moist air currents rise in the atmosphere, ... become so large and heavy that the air currents within the cloud can no longer support them. These water droplets then fall from the cloud as rain (or snow or sleet, depending on the temperature). ...

Atmosphere
The opposite effect occurs in the atmosphere when air descends--it warms ... Figure 5. Figure 5: Breakdown of Walker circulation This change in the atmospheric circulation and water temperatures generally results in increased rainfall in the eastern Pacific (coastal Chile and Peru, for ...

Science and the Environment Bulletin: Network Pinpoints Lightning Strikes
June and August. The circumstances that lead up to a strike occur when hail and supercooled water droplets in a cloud collide, causing them to become electrically charged. The positively charged fragments are carried in the wind to the top of the cloud, while the negatively charged pellets collect in the bottom. Eventually, the ...

Toxic_Fog
All atmospheric water droplets (in rain, cloud and fog) are formed when moisture condenses on particles in the air. ... (e.g. soot, dust, bug fragments etc) and are both soluble and nonsoluble. Because fog droplets are approximately 100 times smaller than raindrops, they can be highly concentrated with respect to the ...

Groundwater and the Water Cycle
The vapors in the clouds condense more and more until they form water droplets. More and more water vapor combines with the water droplet until it is too heavy to stay in the sky ... spaces and cracks between the soil particles on its journey to lower elevations. This movement of water underground is called groundwater flow. Eventually, after years of underground movement, the groundwater comes to a ...

Weather -- The Water Cycle
Oceans formed and the cycle began. Seventy percent of Earth is covered by water. In the atmosphere, rivers, oceans, groundwater, and elsewhere on Earth there are a total of 326 million ... associated with pleasant weather. Stratus clouds, which form in lower parts of the troposphere, consist of water droplets and cover most of the sky with an even, gray color similar to a fog. ...

Oil fate during oil spills in the marine environment
The reverse emulsions, such as oil-in-water (droplets of oil suspended in water), are much less stable because surface-tension forces quickly decrease the dispersion of ... in the open ocean [Benzhitski, 1980]. They complete their cycle by slowly degrading in the water column, on the shore (if they are washed there by currents), or on the sea ...

Oil Water Separators and Separation Systems Operational Theory
Separation Process: The water/oil mixture enters the separator and is spread out horizontally, distributed through an energy and ... to some degree.Due to oil typically being lighter than water, they (oil) will rise up the coalescing plate. As the oil droplets rise up the plate they will coalesce or come ...
