FEBRUARY 2005
March 2005

February continued where January left off: high pressure still anchored to the west of Ireland, but a subtle change brought winds and calm weather from the south east, leading to foggy mornings with bright, sunny afternoons. Freezing fog on the 7th brought the first air frost for 3 weeks and only the seventh of this mild and dry autumn/winter. In mid month the mild air from the SW was replaced by a colder incursion as the high pressure in the Atlantic shifted position enabling the wind to track in from Greenland. The wind has now switched to the NE and E, bringing the first significant snowfall of the winter with some heavy flurries on the evening of the 21st. For the remainder of the month the pattern remained: cold winds, light overnight snow showers leaving a dusting in the morning that melted away quickly during the day, frequent daytime wintry / snow showers.

'WIND ROSE' PLOT FOR THE MONTH
The 'petals' represent wind direction and the length represents frequency, i.e. in this case winds from the north were the most common, followed by the north-north-west.

The colours represent the strength of the wind, with black being weakest through dark and medium blue then lighter colours (cyan, light green, yellow, magenta, red) being stronger.

This data excludes 'calm' readings.
