Question
**Understanding El Nino Influences** During El Nino conditions, which of the following are true? Select ALL that apply. (The map below may help you think about the question.) --- **Map Description** The map indicates geographical points critical for understanding El Nino conditions: 1. **Indonesia**: Marked on the left side of the map and circled for emphasis. 2. **Equator**: Represented by a dashed red line running horizontally, bisecting the map. 3. **Western Pacific Ocean**: Labeled and located to the west of the circled region (Indonesia). 4. **Eastern Pacific Ocean**: Labeled and positioned to the right of the map, along the coasts of South America. The map serves to highlight areas in the Pacific Ocean that undergo significant changes during El Nino events. --- Use the above context and the map to determine the conditions and changes associated with the El Nino phenomenon.

### Oceanographic and Atmospheric Dynamics In studying the intricate dynamics of oceanographic and atmospheric conditions, we observe several phenomena. Below is a detailed checklist highlighting certain key variables. Checked items represent those conditions currently of interest: - ⬜ **Trade winds are stronger than usual** - ✅ **Atmospheric pressure is lower than usual over Indonesia in the western Pacific** - ⬜ **Atmospheric pressure is lower than usual over the eastern tropical Pacific** - ⬜ **Upwelling of cool, deep water is greater than usual along the coast of Peru** - ✅ **Sea surface temperatures are higher than usual in the eastern tropical Pacific** - ⬜ **Sea surface heights are higher than usual in the eastern tropical Pacific** ### Analysis of Conditions #### 1. **Atmospheric Pressure over Indonesia** Currently, atmospheric pressure is noted to be lower than usual over Indonesia in the western Pacific. This can lead to several weather and climate implications, often associated with changes in wind patterns and precipitation. #### 2. **Sea Surface Temperatures in the Eastern Tropical Pacific** There is an observed increase in sea surface temperatures in the eastern tropical Pacific. Elevated sea temperatures can influence weather systems, marine biodiversity, and elevate the potential for phenomena like El Niño. These observations are pivotal for understanding and predicting climatic events and their broader impact on global weather patterns.
