The aggregate description of semi-arid vegetation with precipitation-generated soil moisture heterogeneity

Abstract: Abstract. Meteorological measurements in the Walnut Gulch catchment in Arizona were used to synthesize a distributed, hourly-average time series of data across a 26.9 by 12.5 km area with a grid resolution of 480 m for a continuous 18-month period which included two seasons of monsoonal rainfall. Coupled surface-atmosphere model runs established the acceptability (for modelling purposes) of assuming uniformity in all meteorological variables other than rainfall. Rainfall was interpolated onto the grid from an … Show more

“…Generally, ET and E were high immediately after individual rainfall events, consistent with results reported by White et al (1997). There were, however, a few occasions where the time between the individual rainfall event and the peak ET lagged by one to three days (Figure 3f).…”

“…The seasonal distribution of ET was primarily determined by patterns of precipitation (Wang et al , 2004). After individual rainfall events, ET and evaporation ( E ) increased immediately (White et al , 1997; Wang et al , 2004). This increase in ET was likely due to increased E at the soil surface, rather than increased transpiration (Evans et al , 1981; Wang et al , 2004).…”

“…Generally, high ET values and evaporation followed directly after every large rainfall event (see also e.g. White et al, 1997). Except for a few occasions, the lag time between peak values in ET and individual rainfall events was one to three days (Fig.…”
