Study Notes
SST (Sea Surface Temperature)
-
Definition: SST is the temperature of the ocean's surface layer, typically measured at 1 meter below the surface.
-
Importance:
- Influences weather patterns and climate.
- Affects marine ecosystems and biodiversity.
- Plays a crucial role in ocean circulation and heat distribution.
-
Measurement Methods:
- In Situ Measurements: Buoys, ships, and coastal stations use thermometers or sensors.
- Remote Sensing: Satellites equipped with infrared sensors measure surface temperature from space.
-
Variability:
- Temporal Variability: Changes on daily, seasonal, and annual scales.
- Spatial Variability: Differences in temperature across regions due to factors like currents, winds, and geographical features.
-
Relation to Climate Change:
- Rising SST is an indicator of global warming.
- Warmer SST contributes to more intense storms and hurricanes.
- Affects oceanic carbon absorption and impacts marine life.
-
Applications:
- Weather forecasting: SST data helps predict atmospheric conditions.
- Climate modeling: Essential for understanding and projecting climate change scenarios.
- Fisheries management: Influences fish migration patterns and breeding.
-
Global Patterns:
- Tropics: Generally warm SST with minimal seasonal variation.
- Polar Regions: Cold SST, with seasonal warming during summer months.
- Upwelling Zones: Cooler SST due to nutrient-rich cold water rising to the surface.
-
Anomalies:
- El Niño: Characterized by warmer SST in the central and eastern Pacific, affecting global weather patterns.
- La Niña: Associated with cooler SST in the same regions, leading to different climate impacts.
-
Monitoring Agencies:
- National Oceanic and Atmospheric Administration (NOAA)
- European Space Agency (ESA)
- National Aeronautics and Space Administration (NASA)
Definition and Importance of SST
- SST refers to the temperature of the ocean's surface layer, generally measured at a depth of 1 meter.
- Critical for influencing weather patterns and overall climate, impacting global temperatures.
- Affects marine ecosystems, contributing to biodiversity by dictating species distributions and abundance.
- Essential for ocean circulation and heat distribution, shaping climatic behaviors globally.
Measurement Methods
- In Situ Measurements: Utilize buoys, ships, and coastal stations deploying thermometers or sensors for direct temperature readings.
- Remote Sensing: Employs satellites with infrared sensors to capture surface temperature from a distance, enhancing data collection efficiency.
Variability in SST
- Temporal Variability: Displays fluctuations on daily, seasonal, and annual timescales, influenced by natural cycles.
- Spatial Variability: Exhibits differences across geographical locations due to currents, wind patterns, and local climatic influences.
Relation to Climate Change
- Rising SST serves as a key indicator of global warming, reflecting the planet's increasing temperatures.
- Warmer SST correlates with heightened intensity of storms and hurricanes, leading to exacerbated weather events.
- Impacts oceanic carbon absorption capabilities and disrupts marine life, jeopardizing ecosystems.
Applications of SST Data
- Weather Forecasting: SST data is pivotal for predicting atmospheric conditions, informing short-term and long-term forecasts.
- Climate Modeling: Integral for understanding climate change scenarios and projecting future climate behaviors.
- Fisheries Management: Influences fish migration and breeding patterns, crucial for sustainable fishing practices.
Global Patterns of SST
- Tropics: Typically exhibit warm SST with little seasonal variation, supporting diverse marine environments.
- Polar Regions: Characterized by cold SST, experiencing seasonal warming during summer months which impacts ice coverage and marine life.
- Upwelling Zones: Feature cooler SST due to the rise of nutrient-rich cold water, creating productive fishing areas.
SST Anomalies
- El Niño: Characterized by warmer SST in the central and eastern Pacific, resulting in significant global weather changes, including droughts and floods.
- La Niña: Associated with cooler SST in the same regions, leading to contrasting climatic impacts and shifts in weather patterns.
Monitoring Agencies
- NOAA (National Oceanic and Atmospheric Administration): Monitors SST data for climate understanding and weather forecasting.
- ESA (European Space Agency): Conducts satellite missions to track ocean temperatures and associated environmental changes.
- NASA (National Aeronautics and Space Administration): Provides satellite data crucial for global SST monitoring and research initiatives.
