in order to predict an el niño event, what variables are entered in to the multivariate enso index (mei)?
□ precipitation total
□ density of sea ice
□ sea - level pressure
□ total amount of cloudiness
□ sea surface temperature
□ east - west and north - south velocity components of the trade winds
□ surface - air temperature

Explanation:

The Multivariate ENSO Index (MEI) uses multiple climate - related variables to predict El Niño events. Variables include sea - level pressure, sea surface temperature, east - west and north - south velocity components of the trade winds, surface air temperature, total amount of cloudiness, and precipitation total. Sea ice density is not one of the variables used in the MEI as it is not directly related to the El Niño - Southern Oscillation (ENSO) phenomenon in the same way as the others.

Answer:

• Precipitation total
• Sea - level pressure
• Total amount of cloudiness
• Sea surface temperature
• East - west and north - south velocity components of the trade winds
• Surface air temperature
