Surge Pressure Computations
Surge Pressure Computations. What is a Surge. A pressure surge or a water hammer is a pressure wave caused by a sudden change in water velocity. The word “water hammer” originates from the hammering sound which plumbing makes inside a house when faucets are turned on or off quickly.

El Nino and La Nina
El Nino and La Nina. The most important weather processes after seasons!. Never heard of them! Where are they?. In the Southern Pacific between Australia and South America. So they are nothing to do with Europe?. What kind of Summer weather did the UK have last year? That was La Nina!.

Vorticity
Vorticity. The Law of conservation of Vorticity. Relative vorticity is defined as The time rate of change of vorticity can be written by taking the equations of horizontal momentum and deriving the x component with respect to y and the y component with respect to x

DENSITY
DENSITY. Introduction. What is density?. Density is a comparison of how much matter there is in a certain amount of space. Which one is more dense?. Demonstration: People in a square How about this: Which square is more dense?. Which one is more dense?. Now which one is more dense?.

Enduring Understanding
Enduring Understanding. Energy transfer between the Earth’s surface and the atmosphere creates the weather. The atmosphere remains in balance until acted on by an outside force. Weather. Weather is the current state and short term variations in the state of the atmosphere

5.3 WEATHER FORECASTING
5.3 WEATHER FORECASTING. Air Movement. The movement of air caused by the differences in air pressure is called wind . The greater the pressure difference, the faster the wind moves. Air moves from areas of HIGH pressure into areas of LOW pressure. Air Movement.

Air Pressure and motion
Air Pressure and motion. Air pressure is the weight of air at any particular point. It is also called barometric pressure. The units are given in the ESRT in millibars and inches of mercury and as atmospheres. A barometer is a device used to measure pressure,
