In New Zealand the prevailing wind is from the west or north west, which blows directly across the main mountain ranges. In the right atmospheric conditions this sets up a standing wave in the air passing over the mountains. Depending on the moisture in the airflow this can be indicated by stationary clouds that form in a lenticular shape. The reason that the clouds do not move is that the moisture condenses out of the air as it rises and cools at the front of the wave, then evaporates as the air descends and warms. Thus the air is moving but the cloud remains in place.
This painting shows the leading edge of a lenticular cloud at the right hand side, with a low level cumulus cloud filling the upper left of the picture. The picture can be seen on the Pastel page.
Mana Arts Society
I decided I should support my local arts community, so last week I joined the Mana Arts Society. The society has been going for 30 years, and the 30th anniversary exhibition will be at the Bottle Creek Gallery at Pataka Museum of Arts and Cultures in Porirua. The exhibition runs from 28 March to 15 April and will include two of my paintings - Tararua Sunrise No.s 1 and 2.
The opening is on 1st April and local dignitaries have been invited.
