Thunderstorm

Regardless of the source, the resultant oil slicks are essentially surface phenomena that are affected by several transportation and transformation processes. With respect to transportation, the principal agent for the movement of slicks is the wind, but length scales are important. Whereas small (i.e. relative to the slick size) weather systems, such as thunderstorms, tend to disperse the slick, cyclonic systems can move the slick essentially intact. Advection of a slick is also affected by waves and currents. To a more limited extent, diffusion can also act to transport the oil.

Thunderstorms (cumulonimbus clouds) come in many sizes and shapes, ranging from small air-mass thunderstorms to large supcrcells. Thunderstorms are influenced by the surrounding atmosphere and nearby convective activity. Sometimes a thunderstorm is composed of a single, isolated cumulonimbus cloud. At other times, cumulonimbus clouds are so numerous that they form a continuous sheet, losing any separate identity. 

The air-mass thunderstorm is the least severe of all thunderstorms. In its simplest form, an air-mass thunderstorm grows as a single cell when solar radiation heats the surface air in an unstable atmosphere. Its life cycle lasts around 30 minutes. Towering cumulus clouds are formed as in-cloud updrafts push moisture upward. The tower may reach a height about five times the diameter of the cloud base in the growth phase. 

Most air mass thunderstorms form in groups, facilitating growth by the reduction of cnviroimicntal mixing. These multicellular storms may occur as compact clusters of cells or, if there is some external organization, laterally aligned in squall lines.

Finally, increases in the intensity or variability of weather are considered another form of indirect evidence reflecting whether Earth is currently undergoing human-driven climate change. Predictions of increased incidence of extreme temperatures, tornadoes, thunderstorms, dust storms and fire-promoting weather have been drawn from basic global climate change theoiy. However, evidence has not so far borne out these predictions on a global scale. The IPCC concludes ... 

Most electrical failures are caused by external problems, such as a malfunctioning transformer, a thunderstorm, or a car hitting a power pole. Gas and water pressure failures are often caused by problems within the building itself, such as somebody shutting off a valve in order to make a repair without notifying those concerned. A system must be established whereby all affected by such a shut-down will be informed well in advance. 

The predictions for almost all communities in Canada include more violent winter storms, very high intensity rainfalls of short-duration, and extended heat waves with the accompanying increased risk of smog, wildfires, tree parasites, severe thunderstorms and tornadoes. Current structural design, farming,...

Occurs in the Rhode Island hamlet of Eastwick. Wonderful powers have descended upon Jane, Sukie, and Alexandra now that their husbands are out of the way Alexandra sculpts and creates thunderstorms, Jane plays the cello and can fly through the air, Sukie writes a gossip column and turns milk into cream. Their snug little coven takes on new and more malignant life when a dark, burly and apparently wealthy stranger, Darryl Van Horne, arrives in town he refurbishes the old Lenox mansion, and sets up an alchemist s lab. ..

Figure 6.4 displays the result of this statistical analysis for one single thunderstorm. At the location of the laser filaments (arrow head), 43% (3 out of 7) of the pulses are synchronized with the laser repetition rate, corresponding to a high statistical significance (1 — async = 0.987). The delay mismatch between the RF pulses detected on the different LMA detectors correspond to some tens of meters, typical of spatially spread events, such as a series of... 

Similar results have been obtained during the second thunderstorm [31]. In contrast, no effect was observed when the electric field was low or negative. Therefore, these results suggest that a small fraction (0.24% of the laser pulses, i.e., d event/minute) of the plasma filaments have initiated electric events in a strong positive (upward pointing) electric field [31]. 

Naturally, if an enormous voltage is applied, as in a thunderstorm, the electrons are given so much energy that they are ripped from the valence band and can transfer to the conduction band. In these conditions the insulator is said to break down.
