Ocean Analysis for November 17, 2012
Point #1: Warm finger- This region inside the area marked number 1, represents a warm finger of the ocean temperatures. What is occurring is that the warmer air is being pushed faster in this region than the surrounding locations giving us this little finger of warmer temps in that region.
Point #2: Warm Eddie- This is a region of warmer temps surrounded on all sides by colder water. Eddies are a closed circulation of water in the ocean that has in this case warmer temps around it. These can be important features to pick up on when fishing or doing any kind of ocean sonar work.
Point #3: Cold Finger- The region right alongside Peru is showing a northward push of colder sea temps. This extension of colder temps going into warmer temps is called a cold finger; and also this region is where we find the cold Peru Current. The temps around the region right now are also showing signs of no El-Nino to form as the temps are cooling down.
Point #4: Warm boundary current- The region in area 4 is known as a warm boundary layer current. In the highlighted area you can see the center of the strong push of warmer waters towards the east—this is a boundary that is setting up in the region that will push the stronger, warmer waters slowly towards the east over the next few days.
In summary, knowing some of these features can really help not only meteorologists forecasting the weather but also help fisherman plan where to go fishing. Also, any ocean surveillance that may be taking place can be assessed based of the chart above along with other things. We can also use the above chart to determine where certain features are that can help us monitor the long wave weather pattern over the next few weeks in the United States.
