● A mature tropical cyclone is characterized by the strong spirally circulating wind around the centre, called the eye. ◌ The eye is a region of calm with subsiding air. ◌ Around the eye is the eye-wall, where there is a strong spiralling ascent of air to the greater height reaching the tropopause. ◌ The wind reaches maximum velocity in this region , reaching as high as 250 km per hour. Hence statement 2 is not correct. ◌ Torrential rain occurs here. ◌ From the eyewall, rain bands may radiate and trains of cumulus and cumulonimbus clouds may drift into the outer region.
