Extratropical cyclones, also known as mid-latitude cyclones or wave cyclones, are large-scale weather systems that form in the mid-latitudes between 30 and 60 degrees latitude in both hemispheres. They are distinct from tropical cyclones in several key ways: Formation of Extratropical Cyclones: Impacts of Extratropical Cyclones: Key Takeaways:
Tropical cyclones, also known as hurricanes or typhoons, are powerful storms that form over warm ocean waters. Here’s a breakdown of their mechanism: 1. Warm Ocean Waters: 2. Rising Warm Air: 3. Low-Pressure Center: 4. Coriolis Effect: 5. Eye Formation: 6. Storm Intensification: 7. Weakening: Key Factors for Tropical Cyclone Formation:
Polar winds are prevailing winds that blow from the polar regions towards the equator, roughly between 60° and 90° latitude north and south of the equator. They play a significant role in shaping the climate of polar regions and influencing global atmospheric circulation. Characteristics Types of Polar Winds Impact on Climate Weather Patterns Examples In … Read more
Trade winds are a type of prevailing wind that blows from the east towards the west along the Earth’s equatorial region. They play a significant role in shaping global climate patterns and have been an essential factor in maritime trade and navigation throughout history. Characteristics Impact on Climate Historical Significance Examples
These are the three primary wind belts that encircle the Earth, driven by the uneven heating of the planet by the sun and the Earth’s rotation. 1. Trade Winds 2. Westerlies 3. Polar Winds Key Points:
Atmospheric circulation refers to the large-scale movement of air masses around the Earth. These patterns are driven primarily by solar energy, which heats the planet unevenly, and the Earth’s rotation, which influences the direction of wind flow. Key Components of Atmospheric Circulation: Other Important Features: Significance of Atmospheric Circulation: Key Takeaways:
Ocean deposits are the accumulated materials that settle on the ocean floor. They provide valuable insights into Earth’s history, climate change, and marine ecosystems. These deposits can be broadly classified into two major categories: 1. Organic Deposits: 2. Inorganic Deposits: Significance of Ocean Deposits: Key Takeaways:
What is Salinity? Factors Affecting Ocean Salinity Variations in Ocean Salinity Visual Aid: Significance of Ocean Salinity Key Takeaways:
River Morphology River morphology refers to the shape, size, and characteristics of river channels. It is influenced by a variety of factors, including: Common River Channel Patterns River Landforms Drainage Patterns Drainage patterns are the arrangements of streams and rivers within a drainage basin. They are influenced by the underlying geology and topography. Common … Read more
The hydrological cycle, also known as the water cycle, is the continuous movement of water on, above, and below the surface of the Earth. It’s a vital process that sustains life and shapes our planet’s climate. Key Stages of the Hydrological Cycle: Visual Aid: Significance of the Hydrological Cycle: Human Impact on the Hydrological … Read more
