Wind shear threat data ignored at Mumbai airport, despite repeated incidents

From the year 1985-89 Mumbai Airport received 329 wind shear reports. It happens every year, yet there is no concerted action taken to prevent incidents at Mumbai airport, with the onset of monsoons and rains. The one action which is taken by the regulator is to suspend pilots. They may have a role to play but what about the authorities who have been ignoring data on threats associated with rain and thunderstorm peculiar to Mumbai?
