The satellites measure surface winds near the inner core of a hurricane, such as between the eyewall and the most intense bands of rain, at least a couple of times a day.

At the top of the eyewall, water condenses; as the resulting drops fall back down to the ocean surface they lose power through friction with the surrounding air.
The calmest part — the eye — is surrounded by the most active: a narrow, 15 - kilometer - wide band of wind and rain known as the eyewall.
Circle of Power Surrounding the eye is the eyewall, a hoop of heavy rain and violent winds.
«The eyewall and its updraft typically slope outward at angles from 30 to 60 degrees,» he explains.
Still, he also cautions against the assumption that rainpower is the only factor impacting hurricane intensity, as not all the eyewall's rain falls directly down through the updraft.
This past June scientists at NASA's Stennis Space Center in Mississippi reported that the eyewall's extreme conditions can stir up ocean currents 300 feet below the surface, disrupting sediment and organisms on the seafloor for as long as a week after the storm subsides.
Cyclone Cylinders Huge cloud columns called hot towers may develop in the eyewall and in the bands of rain swirling outward from it.
Through the eyewall flows the updraft, a vertical wind that draws water vapor from the ocean surface.
Activity within the eyewall is closely connected to the hurricane's overall intensity, with the vertical updraft fed by an inward - spiraling, ocean - hugging wind whose average speed is the highest across the whole storm.
Previously, researchers thought rain in the eyewall increased a hurricane's intensity, as heat released from the condensing water added to the overall power of the storm.

Though only 40 miles or so offshore, the eyewall (the engine that drives the rest of the machine) is still over very warm Gulf water.
The EOFs represent these temperatures but also contain additional information about radial structure such as eye size and radial extent of the cold cloud - tops above the eyewall.
The instrument on the Tropical Rainfall Measuring Mission (TRMM) observed two extremely tall complexes of rain clouds called hot towers in the eyewall, a sign that Isaac was trying to strengthen.
Hurricanes (Fig. 7) and other tropical cyclones can be thought of as heat engines that take energy in by evaporating warm ocean water, and eject it at a colder temperature near the tropopause after air rises and water condenses in the eyewall [14].
Hurricanes and other tropical cyclones take energy in by evaporating warm ocean water, and eject it at a colder temperature after air rises and water condenses in the eyewall.

GPM has now captured Matthew near the Florida coast undergoing an eyewall replacement cycle, a process that may re-intensify the storm.
Hurricanes can be thought of, to a first approximation, as a heat engine; obtaining its heat input from the warm, humid air over the tropical ocean, and releasing this heat through the condensation of water vapor into water droplets in deep thunderstorms of the eyewall and rainbands, then giving off a cold exhaust in the upper levels of the troposphere (~ 12 km / 8 mi up).
In a bit of fortunate news, the storm's eyewall, the region with the most destructive winds, had passed to its north.
