Rainfall distribution parameters for selected stations in the four nations of the UK¹⁶.

Country name	Weather station name	Distribution parameters
		ζ (mm−1)	λ (hr−1)	Ψ (hr−1)	θ	${\tilde{V}}_{\text{aat}}$(mm)
England	Heathrow	0.158	0.110	0.012	71	450
Scotland	Turnhouse and Gogarbank	0.165	0.095	0.015	82	500
Wales	Rhoose and St Athan	0.134	0.094	0.017	90	666
Northern Ireland	Aldergrove	0.171	0.095	0.019	103	603

The rainfall distribution parameters were estimated using the method of moments. They are the reciprocals for the mean values of the rainfall event characteristics $(v,t,\text{and}b)$, and ${\tilde{V}}_{\text{aat}}$ represents the average annual total rainfall volume.
