Mostly, when we think of low pressure systems we think of a pretty rainy day. But with this type of warm core center, it generally leads to precipitation occurring overnight, instead of during the daytime when most thunderstorms initiate. Cold core low. Cold core lows are coldest at the center, and no matter which way you go out vertically or horizontally you'll find warmer air. Cold core lows are the most common, and are what we think of when we think of just a regular low pressure system.
They usually lower temperatures, and cause wide-spread showers throughout the day, when there's the most instability caused by heating from the sun. Aleutian low. The Aleutian Low is a semi-permanent low pressure system which persists over the Gulf of Alaska and the Bering Sea and usually leads to numerous storms in the winter. In the summer, the low is very weak, almost non-existent. All rights reserved About Us.
