PLUMP is a one-dimensional time dependent plume model that includes parameterized cloud physics and entrainment. It generates vertical profiles of water vapor, cloud particles, rain and ice, temperature anomaly between the plume and surroundings, and vertical velocity from a vertical sounding of the atmosphere and varying boundary conditions. It is not wind-dependent, modeling only vertical motion in a windless environment. PLUMP can also be used to simulate simple convective clouds, both from orographic lifting and air mass. PLUMP should be useful for prescribed burning and for general smoke management. It will also find use in helping to estimate conditions for lightning activity, fire blowup, and downbursts.
The program (PLUMP.exe) and antecedent files are designed to work in conjunction with John Werth's Weather Service FireWorks program ANALYZE (NOAA, n.d.) for fire weather forecasters, or as a stand-alone program for other users. PLUMP requires 640k memory, DOS 3.1 or higher, color VGA, and a math co-processor to run. The first part of this manual contains instructions for use of the model. A brief description of model workings is given as Appendix A. instructions for using the program with ANALYZE are given in Appendix B.
