percentile) rainfall the scaling with temperature can be as much as twice cc adding the first convection‐resolving model support, at sub‐daily time‐scales, to an increasing body of observational evidence that suggests midlatitude extreme rainfall totals can and do increase by more than the moisture‐holding capacity of the atmosphere when there is an increase in temperature (trenberth et al. by environment division of hunter councils has shown that for the singleton lga there has been a statistically significant decrease in annual rainfall of ~142mm (in the western zone only) over the period from 1948-2007 and a statistically significant annual increase in average maximum temperatures of ~1. climatology including monthly and daily averages and records of temperature and rain. however, lenderink and van meijgaard (2010) have shown through analysis of observations and simulations with two regional models that this is unlikely to be true for summer rainfall.) are recorded in the middle valley near the confluence of the hunter and goulburn rivers, and from this semi-arid core, rainfall totals increase steadily in all directions except westward until the gradients steepen in the high country of the north-east up to 1,200mm/yr.

to provide further insight into the response of convective storms to higher temperatures in otherwise similar atmospheric environments, these experiments should be repeated for a range of case‐studies where extreme rainfall is influenced by forcing mechanisms such as those just described. figure 1 shows hovmüller diagrams of the mean rainfall intensity in the along‐line direction, derived from 5‐minute rainfall accumulations. this hypothesis is supported by the finding that the storm average rainfall exhibits 1. this suggests that either the rainfall intensities responsible for twice cc scaling do not last long enough to be seen in the hourly and longer accumulations, or that they do not remain over a grid square for long enough for accumulations in a grid square to represent the rainfall intensity. we choose the 5‐minute mean vertical velocity since the rainfall intensity is inferred from 5‐minute accumulations, and we define the cloud base as the first eta level above the surface with cloud water mixing ratio greater than zero.

inherent weakness of using daily rainfall statistics from observations and models is that they do not resolve the life cycle of individual storms, and will potentially mask the effects of more intense storms.. rainfall responsethe idealized squall line was modelled for initial 2 m temperatures ranging from 19°c to 29°c at intervals of 1°c. (2009) for summer rainfall in europe when convective systems have a greater influence on the statistics. to old article view go to article navigation abstractthe sensitivity of squall rainfall to changes in atmospheric temperature is investigated. in other words, the extreme values of rainfall intensity in the system scale more strongly with temperature at the expense of the more moderate rainfall.

a conservative revision of pmp estimates assuming up to twice cc scaling for sub‐daily rainfall point and catchment totals should be considered. indeed, one of the main features of extreme rainfall that results in flooding is stationarity, which was not a feature of our experiments. for all periods, the storm average rainfall is found to scale at approximately 1. in our experiments the precipitation efficiency is 100% when the rainfall rate is the maximum, q is constrained by the cc equation and ρ is a constant. percentile of instantaneous rainfall intensity, which is twice cc for temperatures greater than 24°c (figure 2(a)), is consistent with the observations of lenderink and van meijgaard (2008, 2010) for hourly precipitation, who found the increase in scaling to twice cc to occur at maximum daily temperature of around 23°c.
