The multiple physical connections between lightning, convection, precipitation, and rapid storm intensity changes make lightning a rich source of information on how these storms evolve.

It is important to recognize that ΔMLT is a proxy for changing magnitudes of temperature, precipitation, humidity, and CO2, and that both climate and ecosystem inertia also play roles in the relationships between climate forcing and vegetation responses.

That is particularly the case in California, where decadal precipitation variance is typically equivalent to 20 — 50 % of mean annual averages, mostly because of changes in precipitation received between November and March [16 — 17].

Climate change by 2060 was computed as the difference (air temperature) or ratio (precipitation and solar radiation) of monthly mean climate between the GCM (unforced) control and 2xCO2 simulations at GCM grid boxes coinciding with the crop modelling sites (Figure 13.1 b).
