:Perhaps because this increases the air space at the bottom, allowing more air to flow in and thus increase the updraught .-- Shantavira 20 : 55, 28 January 2007 ( UTC)

Various Roman relics have been found along the route in North Staffordshire, including a well-preserved updraught pottery kiln at Trent Vale in Stoke-on-Trent with supporting coin and pottery finds.

The Rumford fireplace created a sensation in London when he introduced the idea of restricting the chimney opening to increase the updraught, which was a much more efficient way to heat a room than earlier fireplaces.

In later times, a fire at the base of a shaft was used to create an updraught, but just like fire-setting, it was a hazardous and dangerous procedure, especially in collieries.

Since the updraught under these clouds ( in the flanking line ) is mainly dynamic, the airmass being smooth and the cloud base higher, a glider pilot could be tempted to fly in this zone.

An airspeed this high is not permissible in turbulent conditions and may lead to break-up of the aircraft . Indeed, when the pilot exits the updraught zone, he will encounter very strong turbulence due to the shear between rising and sinking air.

As such, it had an inline 8-cylinder 2.9-litre engine using two Roots type superchargers fed by two updraught Weber carburettors and fully independent suspension with Dubonnet-type trailing arm suspension with coil springs and hydraulic dampers at front and swing axles with a transverse leaf spring at the rear.
