Identify the incorrect statement on extra-tropical cyclones:

Key Points

• Extra-tropical cyclones are large-scale weather systems that develop in the mid and high latitudes of the Earth.
• They typically have a well-defined frontal system, which is a boundary separating different air masses.
• These cyclones can affect a large geographical area, often larger than tropical cyclones.
• Extra-tropical cyclones can originate over both land and sea, contributing to their widespread impact.

Additional Information

• Extra-tropical Cyclones:
  • These cyclones form outside the tropics, usually between 30° and 60° latitude in both hemispheres.
  • They are associated with weather fronts and a wide variety of weather, including heavy rain, thunderstorms, and snow.
  • Extra-tropical cyclones derive their energy from the horizontal temperature gradients present in the atmosphere, which is different from tropical cyclones that derive energy from warm ocean waters.
  • They play a crucial role in redistributing heat from the equator to the poles, thus influencing global climate patterns.
• Frontal System:
  • A front is a boundary between two different air masses, typically of different temperatures and humidity levels.
  • Fronts are often associated with significant weather changes, including shifts in temperature, wind direction, and precipitation.
  • There are several types of fronts, including cold fronts, warm fronts, stationary fronts, and occluded fronts, each with distinct weather patterns.
• Tropical Cyclones:
  • Tropical cyclones are intense circular storms that originate over warm tropical oceans and are characterized by low atmospheric pressure, high winds, and heavy rain.
  • They are known by different names in different regions, such as hurricanes in the Atlantic and Northeast Pacific, typhoons in the Northwest Pacific, and cyclones in the South Pacific and Indian Ocean.
  • Tropical cyclones have a warm core and derive their energy primarily from the heat of the sea surface.
