    Is it something to do with the troposphere having less depth over here than in the states, that our hail is always much smaller in severe showers?

    The troposphere is not necessarily deeper over there on any one day, it varies greatly from day to day and region to region. The main factor in large hail is massive amounts of CAPE, which we don't get to the same extent as over there. Other factors such as dry mid levels, wind shear and low wet-bulb zero levels and low precipitable water levels we do get, but without the high CAPE, we just won't get much more than pea-sized hail, which we got today. Elevation is also a factor, which we don't do too well here either.

    Here's an interesting article about the role of bacteria in the formation of hail..
