wake turbulence

wake turbulence
The disturbed air left behind by an airplane. It consists of wing-tip vortices and a jet blast, jet wash, propeller wash, and rotor wash, both on the ground and in the air. It is the region of reduced total pressure behind an aircraft in flight.

The new lidar has a vertical spatial resolution of 10 meters, making it well-suited for measuring small-scale phenomena such as wind shear and aircraft-generated wake turbulence.
Though even nine miles apart seems far enough to avoid any chance of collision, the minimum legal distances of ten miles and 1,000 feet are chosen not only because of the primary factor of a possible collision, but also the effects of secondary factors such as sudden changes in the weather conditions and wake turbulence, the disturbance which forms as an aircraft passes through the air.
There was a six knot crosswind, so I told the tower controller that we would waive the wake turbulence hold and were ready to go.
The controller in the tower called and in a somewhat shaken voice (I assume he had witnessed my roller-coaster ride), stated I needed to hold for a minute or two to avoid wake turbulence.

on November 2, Department of Transportation (DOT) Secretary Anthony Foxx said the DOT estimates that NextGen has already produced nearly $2 billion in benefits through improvements such as recategorizing wake turbulence separations and implementing satellite-based arrival and departure procedures.
The call sign "heavy" set off an immediate alarm in my head to be cautious about wake turbulence.
One of the wake projects is called RECAT which is designed to recategorise the existing four wake turbulence categories into six new wake categories.

Now, while getting far from the model, turbulence profile indentation gets flatter and includes larger surface behind the model which means by getting far from the back of vehicle, amount of wake turbulence initially increases and then decreases.
