I believe that a 'dynamic low' is produced by The strong rise of air.
A dynamic low develops if the air flow converges in lower regions of the atmosphere and diverges in altitude while the air is kept up in the center of the low. A low pressure area is a region on the topographic map where the atmospheric pressure is lower than that surrounding locations. Low pressure systems form under areas of wind divergence that occur in the upper levels of the troposphere.
Because you will focus past ("overshoot") your specimen. (Like using a race car as a shopping cart: it's too fast, and you'll fly past the cereal and never even see it before you realize you need to stop.) Also: you risk crushing the slide and objective against each other (on older or cheaper scopes), and that would be a costly (and embarrassing) mistake.
