In fact, you can have a very nice weather in a high pressure zone, with clear sunny sky and little wind, but during daytime, the pressure drops a little to climb up again during the night. That is a normal diurnal variation of pressure; when it is hot, air rises and pressure drops a bit. It is not the drop in itself but the rate of fall that is the most important point and that's why some people have barographs that register the pressure over time. An old seafarer's rule is that a pressure fall of ten millibars (today, called hecto-Pascal) in eight hours is a certain sign of a gale force wind coming in. And that is the only thing that is 100 percent certain in meteorology; a pressure fall must be followed by a wind of air trying to fill again the lower pressure.
Causes Of Enlarged Kidneys In Fetus.

Usually, no protein is found in urine because most proteins are too big to go through the kidneys. If your doctor finds protein in your child's urine, it means your child's kidneys may not be working as they should--possibly because of inflammation (swelling).Sometimes infection or chemicals damage the kidneys, and this makes protein show up in the urine.roteinuria doesn't cause pain. But when a lot of protein is in the urine, the level of protein in the blood may go down. This can cause swelling in your child's eyelids, ankles and legs. High blood pressure is another sign of this problem.
