1. **Depth of El Niño (Surface to Thermocline):** In an El Niño event, the sea surface temperature increases significantly, often leading to changes in the depth of the thermocline. The thermocline is typically found at depths of about 50 to 150 meters (164 to 492 feet) in the Eastern Pacific. During an El Niño event, the thermocline can become shallower in the eastern Pacific, with warmer surface waters causing the thermocline to rise. However, the exact depth of the thermocline can vary based on the specific event and prevailing atmospheric conditions.
2. **Direct Relationship between Temperature and Climate Extremes:** There tends to be a correlation between the intensity of El Niño (often indicated by sea surface temperature anomalies) and the severity of the climate impacts it causes, such as extreme weather events. Warmer sea surface temperatures can enhance rainfall patterns, affect storm tracks, and increase the likelihood and intensity of extreme weather events (like floods, droughts, and hurricanes). However, many other factors influence climate extremes, so the relationship is not always straightforward.
3. **Impact of a Five-Degree Change in El Niño Temperature:** A substantial change, such as a five-degree increase in ocean temperatures during an El Niño event, could potentially lead to significant impacts on weather patterns and climate extremes. Research has indicated that higher sea surface temperatures can intensify the atmospheric responses, leading to more extreme rainfall, droughts, or cyclones. The degree of impact would depend on existing conditions, the geographic areas affected, and other climatic variables, but such a temperature change could likely result in more severe or frequent climate-related issues.
In summary, an escalation in sea surface temperatures during an El Niño event would have the potential to exacerbate the extremity and frequency of climate impacts.
