1) Let's look at the structure of the equatorial thermocline during an El Niño event and during a La Niña event, by analyzing data from the TAO Array in the Tropical Pacific.
i. Navigate to the following website https://www.pmel.noaa.gov/tao/drupal/disdel/
ii. Click on "Lat Lon Map"
iii. Click on "Two Dates"
iv. Set one date to Nov 30, 2020, and the other to Nov. 30, 2015.
v. Click on "Display"
a. Describe the difference in surface temperature and wind fields from the two figures. Focus on surface temperature in the central and eastern equatorial region (east of about 180°), and wind in the central and western equatorial region (focus on the east / west component of the wind).
b. Now, repeat the instructions above, but instead of "Lat Lon Map", click on "Depth Section" to show the structure of the equatorial thermocline. Describe the difference in structure between the two figures, focusing on the thermocline depth in the western Pacific, between about 100°W and 140°W.
c. Which date corresponds to an El Niño event, and which corresponds to a La Niña event?
d. (Problem 1, continued) Describe how the feedback between wind, thermocline depth, upwelling, and sea surface temperature leads to the development of an El Niño event.
