Question: For this activity, you'll need to analyze and draw some conclusions from the plot of Sea-Surface Temperature Anomalies across the central and eastern Pacific above. The map covers the three-month period from December through February (meteorological winter in the Northern Hemisphere) in an unknown year. Recall that sea-surface temperature anomalies show the difference between the sea-surface temperatures during this particular three-month period and the long-term average for December - February. For reference, the anomaly calculation is: anomaly = actual observation - long-term average.

Would these sea-surface temperature anomalies be indicative of an El Niño, La Niña, or neutral ENSO state (with neither El Niño or La Niña)?

What is the value of the largest temperature anomaly across the central and eastern equatorial Pacific (within 5 degrees latitude of the equator)? Make sure to include proper units! Does this value represent warmer-than-normal or colder-than-normal conditions?

Which of the following changes to the trade winds was most likely associated with the development of these sea-surface temperature anomalies: a strengthening of the trade winds, or a weakening of the trade winds?

Given the sea-surface temperature anomalies above, which of the following changes to the subtropical jet stream would most likely develop over time, as overlying air columns become modified: a strengthening of the subtropical jet stream, or a weakening of the subtropical jet stream?

Finally, consider this plot of Precipitation-Rate Anomalies across the central and eastern Pacific during the same period below. Do the precipitation-rate anomalies within 5-degrees latitude of the equator largely represent wetter-than-normal or drier-than-normal conditions? Briefly explain these anomalies based on expected changes to the Walker Circulation that relate to the answers to questions 1 and 2.
