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.
Answer:
Cyanobacteria are aquatic and photosynthetic, that is, they live in the water, and can manufacture their own food. Because they are bacteria, they are quite small and usually unicellular, though they often grow in colonies large enough to see. They have the distinction of being the oldest known fossils, more than 3.5 billion years old, in fact! It may surprise you then to know that the cyanobacteria are still around; they are one of the largest and most important groups of bacteria on earth.
Tons of rain can cause an ecosystem to flood, killing species that are not meant to withstand lots of water. Ocean temperature can slow down or speed up evaporation, affecting precipitation rates.
