Study Notes
SST (Sea Surface Temperature)
- SST stands for Sea Surface Temperature.
- Sea Surface Temperature (SST) refers to the water temperature at the ocean's surface.
- SST typically measures the temperature within the top millimeter to several meters of the ocean's surface.
- SST is a crucial indicator of climate change, weather patterns, and ocean conditions.
- SST influences atmospheric processes, marine ecosystems, and global climate patterns.
- Data is collected using satellite observations, buoys, and ship-based measurements.
- Satellite-based SST measurements provide global coverage and high spatial resolution.
- Buoys and ship-based measurements offer more accurate and in-situ SST data.
- SST data is used in weather forecasting models to improve accuracy.
- SST affects the formation and intensity of tropical cyclones and hurricanes.
- Warm SST can provide energy for storms to intensify.
- SST is used to monitor and study El Niño and La Niña events.
- El Niño is characterized by unusually warm SST in the central and eastern tropical Pacific Ocean.
- La Niña is characterized by unusually cold SST in the same region.
- SST affects the distribution and behavior of marine life, including fish, coral reefs, and marine mammals.
- Changes in SST can lead to coral bleaching events.
- SST is used to study ocean currents and their effects on heat transport.
- SST data helps scientists understand long-term climate trends and variability.
Globes
- A globe is a three-dimensional scale model of the Earth (or other celestial body).
- Globes represent the Earth's shape, continents, oceans, and other geographical features accurately.
- Globes are typically spherical to minimize distortion of shapes and distances.
- Can be physical, political, or thematic, showing different types of information.
- Physical globes emphasize natural features like mountains, deserts, and rivers.
- Political globes show countries, cities, and political boundaries.
- Thematic globes display specific data, such as population density, climate, or resources.
- Globes use a coordinate system of latitude and longitude to locate points on the Earth's surface.
- Latitude lines (parallels) run horizontally around the globe, measuring distance north or south of the equator.
- The equator is 0° latitude and divides the Earth into the Northern and Southern Hemispheres.
- Longitude lines (meridians) run vertically from the North Pole to the South Pole, measuring distance east or west of the Prime Meridian.
- The Prime Meridian is 0° longitude and passes through Greenwich, England.
- Globes can be used to visualize the Earth's rotation and revolution around the Sun.
- The tilt of the Earth's axis, as represented on a globe, explains the seasons.
- Some globes include additional features, such as raised relief to show topography and illuminated interiors.
- Globes are used in education, navigation, and geographical studies.
- Globes help to develop spatial awareness and understanding of global relationships.
Maps
- A map is a two-dimensional representation of the Earth's surface or a portion of it.
- Maps use symbols, colors, and labels to represent different features.
- Maps are inherently distorted because they flatten a curved surface onto a plane.
- Map projections are used to minimize distortion, but all projections have some limitations.
- Common map projections include Mercator, Robinson, and azimuthal projections.
- The Mercator projection preserves shape and direction but distorts area, especially at high latitudes.
- The Robinson projection provides a compromise between shape, area, and direction, making it suitable for general-purpose maps.
- Azimuthal projections preserve direction from a central point, useful for navigation and polar regions.
- Maps can be physical, political, thematic, or topographic.
- Physical maps show natural features such as mountains, rivers, and deserts.
- Political maps show countries, states, cities, and political boundaries.
- Thematic maps display specific information, such as population density, climate, or economic activity.
- Topographic maps show elevation changes using contour lines.
- Maps use a scale to represent the relationship between distances on the map and corresponding distances on the ground.
- Map scales can be represented as a ratio (e.g., 1:100,000), a verbal statement (e.g., 1 inch equals 1 mile), or a graphic scale (bar scale).
- Maps include a legend or key to explain the symbols and colors used.
- Maps often include a compass rose or north arrow to indicate direction.
- Geographic Information Systems (GIS) are used to create, analyze, and visualize spatial data on maps.
- Maps are used in navigation, urban planning, environmental management, and many other fields.
- Digital maps and online mapping services have revolutionized map usage and accessibility.
SST in Relation to Globes and Maps
- SST data can be represented on both globes and maps.
- On globes, SST can be displayed as a thematic layer, with colors indicating different temperature ranges.
- Globes provide a realistic representation of the Earth's shape, allowing for accurate visualization of SST patterns.
- On maps, SST can be displayed using various techniques, such as color gradients, contour lines (isotherms), or symbols.
- Maps allow for more detailed representation of SST data, especially for specific regions.
- Map projections must be considered when displaying SST data to minimize distortion of areas and shapes.
- GIS software is commonly used to create SST maps and analyze spatial patterns.
- SST data displayed on globes and maps can be used to monitor climate change, ocean currents, and marine ecosystems.
- Satellite-derived SST data is often used to create global SST maps, providing a comprehensive view of ocean temperatures.
- SST maps can be used to track the movement and intensity of warm and cold water masses.
- SST maps are essential tools for weather forecasting, climate modeling, and marine research.
