MARCH 2005
|
||
|
Very much "a month of two
halves", starting where February left off: cold and windy with frequent
wintry showers. In spite of this, Tonbridge remained free of the snow
cover which affected other nearby towns, particularly on the 2nd. The
minimum temperature of -4.5º on the 4th was a new record March low
for this site. The persistant blocking high to the NW of the British Isles
finally started to decline in the 2nd week. The first half of this month
was the coldest start to a March since 1987. A complete change on the
16th as mild southerly air brought the highest maximum temperature since
the 30th September, and the 19th set a new site record for maximum temperature
in March, beating the previous record of 20.3º in 1990. The month
ended on a calm, cloudy, gloomy and damp note, but in spite of this, March
was the 5th consecutive month with rainfall total significantly below
average.

'WIND ROSE' PLOT FOR THE MONTH
|
|
 |
The 'petals' represent wind direction and the length
represents frequency, i.e. in this case winds from the SSW were the most
common, followed by the N. The colours represent the strength of the wind, with black being weakest through blue then lighter colours (cyan, light green, yellow, magenta, red) being stronger. This data excludes 'calm' readings. |
