FEBRUARY 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. |
