Hurricane eye satellite

The eye of a hurricane is a calm central region with clear skies and light winds, surrounded by the eyewall where the strongest winds occur.

About this subject

Hurricanes, also known as tropical cyclones, are low-pressure systems that form over warm ocean waters. The eye is a distinctive feature of mature hurricanes, typically measuring 30 to 65 kilometers in diameter, though it can vary. Inside the eye, air descends slowly, resulting in higher temperatures and cloud-free skies. The eyewall, a ring of convective storms, is where the most violent winds and heaviest precipitation occur. Satellite observation allows real-time monitoring of eye evolution, crucial for track and intensity forecasts. Hurricanes such as Katrina (2005) and Irma (2017) had well-defined eyes, aiding tracking by weather satellites. Eye formation indicates that the hurricane has reached maturity with a well-organized circulation.

Frequently Asked Questions

What causes the formation of a hurricane eye?

The eye forms when centrifugal forces and updrafts in the eyewall create a region of subsidence at the center, warming the air and evaporating clouds.

Is the eye of a hurricane always visible in satellite images?

Not always. Developing hurricanes may have cloudy or ill-defined eyes. Infrared satellites can detect the structure even under cloud cover.

What is the difference between the eye and the eyewall?

The eye is the calm, cloud-free central region. The eyewall is the ring of storms around it, where winds are strongest and heavy rain occurs.
