Weather thunderstorms

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. 

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 ... 

AM. Severe thunderstorm starts. (Interviews) Ambient temperature 85°F, NW winds 3mph (Plant weather station log)... 

The Parkinsons have decided to cancel their Saturday afternoon barbeque by the pool while the weather forecast is calling for massive thunderstorms throughout the entire weekend. 

According to the weather report, there are three thunderstorms in the area and if they connect. it is going to be an extremely powerful system. 

After a fast passage of the cloud-poor weather period of the gale—with developed gale and Baltic Sea waves—the clouds increase again rapidly and strong shower fronts with thunderstorm and hail follow (Fig. 4.7). 

Environmental influences on asthma were recognised by Hippocrates more than 2,000 years ago. In the 19th century, known associations with asthma included the weather, air temperature, humidity, thunderstorms, environmental tobacco smoke (ETS), fenny country, season, occupation, diet, exercise, feather beds, animals, pollen and the passions . The only major risk factor not noted in the 19th century was infection, due to the lack of germ theory. However, there was no formal asthma and allergy epidemiology until the 20th century. 

Any one of the properties or conditions of the atmosphere which together specify the weather at a given place for any particular time (for example, air temperature, pressure, wind, humidity, thunderstorm and fog). 

When we have equal molar masses of two gases at the same pressure but different temperatures, the hotter gas is less dense than the cooler one, so the hotter gas rises. The difference between the densities of hot and cold air is responsible for the lift of hot-air balloons. It is also responsible for many phenomena in weather, such as the formation of large thunderhead clouds during thunderstorms. 

Regardless of the location of a facility, there are bound to be occasional weather issues. Blizzards, hurricanes, severe thunderstorms, and tornadoes are some examples of natural phenomena that can have an unpredictable impact on operations. Emergencies within the facility, such as a fire or explosion, can also create extreme confusion and necessitate swift actions to prevent escalation of the emergency. When a unit or an entire facility only maintains the minimum number of employees required to complete job duties at any given time, unexpected upsets such as erratic weather conditions or plant emergencies can wreak havoc on a workforce that is already barely adequate. 

Troposphere The layer of the atmosphere between the ground and the stratosphere the troposphere is the layer where all weather phenomena (fronts, thunderstorms, hurricanes, etc.) take place. 

Thunderstorm currents totaling 1500 A flow to the ionosphere, which is an approximately equipotential layer in the upper atmosphere, and return to earth in fair-weather regions. The resistance between the ionosphere and earth is 200 f2, giving rise to an ionospheric potential of 300 kV. The vertical electric field near the earth s surface is of the order of 100 V/m, and the associated current density is typically several picoamperes/m. The ac component of the fair-weather field is relatively much smaller than the ac component of individual thunderstorm currents.
