Can they then
move closer to the equator than that after forming ?
No.
The steering winds are away from the equator. Most TCs form around 10
degrees north and south. The three requirements for a TC are the sea
surface temperature, the latitude and a pre-existing low pressure system.
This is the monsoon trough. It is currently still just north of Australia
which is why TC "Alistair" was able to form.
Tropical Cyclone
movement is, however, erratic. Individual storms can move in any direction
for short periods, including north towards the equator but they never get
closer to the equator than 5 degrees.
Places on and close to the
equator do not get TCs and TCs cannot cross the
equator.
