the Philippines area of responsibility (PAR) are considered in the validation presented here. Annual TC frequencies, and frequencies of the more intense TCs (above 33m/s), are shown in figure 14. The results show comparable values to the observations for the total number of TCs in the simulations driven

. Towards mid-month it became more settled generally, with high pressure in charge for much of the rest of the month, though much of the final week was rather cooler. Clear skies ensured that sunshine totals were above average in many areas, but there were more air frosts than average. The provisional

the long-term average, with overnight temperatures being lowest relative to average. Scotland had 39% of average rainfall, provisionally the sixth driest April in a series from 1862, though with parts of northern Scotland getting relatively close to their average rainfall totals. Sunshine totals were 160

provisionally 1.1 °C above average, with warmth by day but overnight temperatures no higher than average. It was a dry month with only 50% of average rainfall. There was also plenty of sunshine, this totalling 144% of average. 1st to 7th The 1st began clear and cold in the north, cloudier in the south
