Many know and understand how barometric pressure systems work, but if you don't, maybe this thread can help you with some good insight, assuming it's provided.
Pressure is seperated by (H) and (L) or high and low. To understand the difference is simple, a Low pressure system generally creates overcast skies with precipitation and storms, where as a High pressure system relates more to bright blue bird days of sun. So another way to think of it if you're a waterfowl hunter, (L) pressure days are best for low flying birds and (H) pressure days are the high flying days or basically, the day you go pheasant or bow deer hunting instead.
This may be a little too technical, but scuba divers know that as you go down to greater depths, the water pressure increases. In fact, the increase in pressure is 14.7 psi for every 34 feet of additional depth.
This pressure is in addition to the normal atmospheric pressure at the surface. The pressure limits the depth to which unprotected divers can go, and the pressure causes lots of problems. The point is that as you descend deeper into a fluid, whether it be water or air or whatever, the pressure increases. And if you go upward toward the surface, the pressure becomes less. I POSE THIS QUESTION: As air pressure is heavy and pushes down on the earth like a heavy blanket when the pressure is high, water should subsequently be pushed down as well, such that perhaps water levels should slightly rise, even if un-noticable. Would this have any effect on fish suspension in the variable water column. Will fish suspend higher in high pressure systems and visa-versa.
Generally, I think of fish sitting on the bottom on bright sunny days, and suspending in the dark and on overcast days. The same for feeding activity, that being less on sunny days, more on overcast days and nightime.
As a musky fisherman, I tend to pay a lot of attention to the Baro Pressure daily, and relate that to the time of year and the differences it might make in my success rate for that particular day/outing. Generally, I lean towards low pressure days as my favorites, especially if I can beat the rain/storm by a couple hours to reap the benefits of pre-frontal windows of opportunity. However, lately, I have been on a hot pattern on a couple of our SE WI musky lakes that has only been showing it's true colors during (H) pressure days. Such that, today, as soon as I get out of work, I'll be on my way out to Pewaukee Lake.
Any insight? What are your opinions. Other species react differently, what do you target and what kind of weather patterns do you favor or lean towards?
