1 Do not apply the ice directly to the knee; instead, cover your knee with a cotton towel. 2  Place ice in a plastic zip-close bag, and then place the bag on the towel. 3  Wear cushioned, flat shoes that support your feet and donât exacerbate your pain. 4  Avoid sleeping on your side.
A simple and general rule-of-thumb for estimating a storm's low pressure contribution to the surge is as follows: 1 cm of rise above predicted tidal values for each 1 hPa below the standard atmospheric pressure of 1013 hPa. For example, Hurricane Juan had a central pressure of 974 hPa when it made landfall just west of Halifax Harbour. The pressure effect alone would result in a surge of approximately 39 cm, however, the surge measured in Halifax Harbour was about 150 cm. Clearly, a more important mechanism was at work. The wind is the key.
Barometric pressure is the weight of the overlying air pressing down on the earth. It is also known as air pressure. Low barometric pressure means the overlying air is rising, whereas high pressure means the overlying air is sinking. Barometric pressure has important effects on water chemistry and weather conditions. It affects the amount of gas that can dissolve in water. More gas, such as oxygen, can dissolve in water under higher pressure when compared to lower air pressure. For instance, more oxygen is dissolved in water at sea level than at high altitudes. The pressure of the overlying air forces more gas into solution. As the overlying pressure decreases, gas is released from solution.
