When an invest is started, it triggers special data collection at a number of web sites, including the NRL and FNMOC TC web pages, UW/CIMSS, and others. These web sites provide NHC and JTWC with things like microwave data processing, and AMSU analyses over the disturbance that would not be available any other way. An invest may represent nothing more than a desire on the part of the forecaster to see microwave imagery, for example. Or in a non-tropical low, the AMSU data to investigate the development of an upper warm core.
These invests don't "cost" anything (even the disk space the imagery generates gets recycled), so who cares if a million of them get started.
True, and since they are initiated by the Navy, it could just be that an upper level low or weak tropical wave moves over an area where ships are holding excercises and they want to keep an eye on it for squally weather that would only hinder their operations. So with 95L East of the Bahamas, there could be a ship holding a missile test and they want to know the wind patterns above.
