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 and Weather Conditions. General Observations. Low and High Air Pressure Low air pressure= less weight pushing down= air is rising and cooling which helps form clouds. High air pressure= more weight pushing down= air is sinking and warming with less humidity. Falling or Low Barometric Pressure Deteriorating weather or some form of precipitation such as wet and/or windy conditions and thunder in hot weather are associated with falling barometric pressure. As a storm approaches air pressure begins to fall and this can happen very quickly.
