A tornado is in cyclostrophic balance where the horizontal pressure gradient and centrifugal forces balance each other. Consider a tornado with 100 m radius and a tangential velocity of 100 m s⁻¹ at the edge. Assuming air density = 1 kg m⁻³, the magnitude of the pressure-drop between the centre and the edge of the tornado is ______ kg m⁻¹ s⁻².
