Table 2. Matrix probabilities assigned to stochastic models for precipitation patterns in the last 8 and 100 years, and scenarios of increasing aridity by 20% and 40%. The classification of Wet or Dry Transition Years is based upon precipitation in Tuzigoot, Arizona in 1995-2003. Precipitation at Tuzigoot, Arizona was above average in 1997, 1998, and 2000 and was below average in all other years of the study.

Classification	Transition	Random	Last 100 yrs	20% More Arid	40% More Arid
Dry	1996-1997	0.143	0.104	0.144	0.184

Wet	1997-1998	0.143	0.240	0.140	0.040

Dry	1998-1999	0.143	0.104	0.144	0.184

Dry	1999-2000	0.143	0.104	0.144	0.184

Wet	2000-2001	0.143	0.240	0.140	0.040

Dry	2001-2002	0.143	0.104	0.144	0.184

Dry	2002-2003	0.143	0.104	0.144	0.184
