I'm trying to put the formation of a tropical cyclone in order, but I'm a bit confused on these two terms. In the formation of a tropical cyclone, which would come first a disturbance or a invest?
I define a tropical disturbance as a weather system with organized convection originating from the tropics that has a non-frontal migratory characteristic and maintains its identity for at least 24 hours.
Then I define invest as an investigative area of weather (that has the potential to form into a tropical cyclone) that a forecast center collects data on and is labeled 90-99, with a corresponding letter for each ocean basin.
The order I have currently is:
Tropical Wave (Easterly Wave)
Tropical Disturbance
Tropical Depression
Tropical Storm
Subtropical Storm
Extratropical Storm (Mid-Latitude Cyclones or Wave Cyclones)
What comes first a Tropical Disturbance and an Invest?
