That said, Caldeira emphasizes, either variety of geoengineering doing it uniformly at the pole or the geographically optimized version have shown less total warming and less disruption of rain patterns.
Models can be used to vary systematically and in combination characteristics of rain patterns, soil properties, and plant functional types, which would otherwise be hard to achieve logistically or technically in experiments.
The shift of rain pattern had clear effects on the average longest wet period (LWP; Fig. 2A, B).
Simulations with a seed bank that carries over to the following year was conducted to assess the consequences of change of rain pattern on population persistence.
Extending the model to simulate individuals of several species or functional types simultaneously would allow studying effects of rain pattern on, e.g., community composition or invisibility.
The resetting allowed the analysis of rain pattern effects without the influence of inter-annual carry-over effects caused by sequences of wet or dry years.
Thus, the manipulation of rain pattern shifted the distribution of daily rain volumes to more frequent heavy rainfalls at the cost of light rains as observed in the Mediterranean [ 7].
Among the many vegetation and soil variables simulated by the model, I concentrated on formally analyzing the effect of rain pattern on annual longest wet period (LWP), seedling density, and peak shoot mass (maximum annual aboveground biomass) because each is an integrative measure of, respectively, available soil moisture, establishment, and community performance.
For the assessment of rain pattern effects on LWP, seedling density, and peak biomass, seed bank density in each region was reset to a constant value at the beginning of each vegetation year (AR: 2000, SA: 16000, DM: 17000, TM: 18000, MM: 20000 seeds/m2 corresponding to typical values observed in the field).
FMWD General Manager Nina Jazmadarian urged residents to plan for upcoming dry months by taking advantage of winter rain patterns now.
The interaction between rainfall variability, soil texture, and water recharge has been described qualitatively by Noy-Meir as the 'inverse texture effect' [ 1], but the effect of different rain patterns on plant growth in arid and mesic regions has not been studied and quantified yet.
