of upwelling and some sites where water descends mostly in areas of convergence of warm and cold currents in the Polar Regions. What is upwelling exactly? It is an oceanographic phenomenon with large biological implications. Precisely it is the wind driven movement of dense‚ cooler and nutrient rich water from below the photic zone‚ replacing the warmer‚ usually nutrient-deficient surface water. The reason why this layer of water is nutrient rich is that the density gradient of oceans falls rises

TORNADO SYNOPSIS OF THE EL RENO TORNADO Introduction Tornadoes are violent storms that look like black‚ funnel shaped clouds. The wind of these storms can reach a speed of 500 kilometers per hour (310 miles per hour). Tornadoes are capable of destroying everything on their path. Tornadoes are usually the extreme result of a very large thunderstorm called a supercell. During the storm cold air and warm air combine. The cold air goes drops as the warm air rises. The warm air eventually twists

transpiration was measured in different surrounding’s conditions‚ including temperature‚ light and wind force. Thirdly‚ the rate of transpiration was measured under standard conditions in order to make easy to compare normal rate and affected rate. Therefore‚ several hypothesizes can take place in this experiment. Firstly‚ the rate of transpiration will increase by increasing the intensity of light. Secondly‚ if the wind forces increase‚ the rate of transpiration will also increase. And thirdly‚ if the temperature

and water from these tubes enters the drum. Convection superheater The steam produced in the boiler is nearly saturated. This steam as such should not be used in the steam turbine. The presence of moisture in it will cause corrosion of turbine blades‚ etc. to raise the temperature of steam and thereby to increase the turbine efficiency‚ superheater is used. The principle of convection superheater is similar to steam generating tubes of the boiler. The hot flue gases at high temperature sweep over

cyclone”. These can also be identified as typhoons.The tropical storms winds must reach at least 74 mph to be considered a hurricane. Anything below this is just considered a tropical depression or a tropical storm. Hurricanes usually only occur in the Atlantic Hurricane season (June 1-November 30). Hurricanes form over warm ocean water. They use the warm moist air as fuel at the bottom of the hurricane. As the huge storm produces high wind speeds‚ it causes water to evaporate.The water vapor evaporates

pollutants than smaller smoke stacks because of the greater volume of air. A taller smoke stack would generally improve the air quality in the surrounding area but would also cause a larger area to be polluted because it would be pushed out further by the winds. During the cooler parts of the day‚ which is considered a stable inversion‚ the taller stack is able to disperse the smoke over a larger area rather than a smaller smoke stack which contaminates the surrounding area more in the relatively unstable

1. The larger pebbles tend to build up making the slope bumpy(less steep) however smaller ones will spread out and even out more making the slope smoother‚ steeper. 2. The wind is stronger in some parts of porlock bay than others‚ making waves stronger and more powerful. I think wind is the most important factor. 3. I think the steepest beach will be Hurlstone because it’s the end of the beach where pebbles will be at their smallest and roundest due to erosion.

To be prepared for a tornado or hurricane you must know three biggest effects they can have‚ enormous wind‚ gigantic size‚ and were 90 percent of time are located. To begin with‚ the first effects is their heavy-duty wind. Their heavy-duty wind is one of the most dangerous effects a hurricane or tornadoes.

You’re not sure if that is completely accurate information because you can hear the wind around you picking up‚ rapidly. You look out your window‚ just to see the tornado forming. The thunderstorm outside has touched the ground! The meteorologist sets out a warning. You speed to you basement and have no time to rush to get all of your
