AVN tropical storm track status with MRFX

Tropical storm track (72-hr fcst) status with MRFX

summer 2000 parallel using sas01 with random cloud top selection and momentum mixing by convection

summer 2000 parallel X. part of it with random cloud top part with deepest cloud top

Floyd tests

Example of the relocation algorithm

These are the storm track stats for convection change with a relocation that was only correcting to the within 15 km. EXP2 is the test package results

tropical storm track verification for 1999 compared with other operational center results

The following gif file shows the comparison of the experimental runs with the operational AVN runs. (EXP1 convection change with a relocation that is to the nearest degree lat/long point, EXP2 convection change and relocation to the nearest 15 km)

tropical storm track verification for 1999

The following two figures are precipitation scores for U.S. for the convection test. For these scores, PRY stood for the experimental convection runs.

T126 Precip threat score for August 1999

T126 Precip bias score for August 1999

Following are a set of month long assimilation and forecast results using T62 system to test tropical climate response to convection change. prq is the designated name for the experimental runs while pra is the control.
