What Happens To Our Weather BY FRANK THOMPSON NTARIO residents have the reputation of being amongst the most weather conscious people in the world. Visitors from other countries are impresed by the extent to which the weather is a topic of conversation, the amount of speculation on what tomorrow will be, and the exten- sive coverage given weather forecasts by the press and radio. This interest probably results from the fact that our weather is rarely monotonous, but varies greatly from day to day. ! Gigantic eddies of air, usually referred to as high and low pressure systems, are continually moving eastward across south- ern Canada and the northern United States. As the eddies progress our winds are constantly shifting from northerly to 'southerly and back again to northerly. A glance at a map of North America reveals that to the north of this province lies - Hudson Bay, and to the south the United States, beyond which lie the warm waters of the Gulf of Mexico. As a result, Ontario is periodically invaded by cold blasts of air from the north and northwest followed by warm blasts from the south and south- west. In summer, Hudson Bay remains a vast reservoir of cold. Ice floes frequently hamper shipping as late as early July. it may be thought of as a gigantic refrige- rator, or as a projection of the Arctic seas southward into the heart of the continent. When winds blow off of Hudson Bay in summer, dull overcast skies prevail over Northern Ontario. Temperatures are low and drizzly rain frequently occurs, parti- cularly during the morning. If the north- erly winds are strong enough, they will transport the cold air farther south into southern Ontario. The farther south the air moves the more it is warmed by the sun and conse- quently these periodic cold outbreaks are felt less in Muskoka than in Northern Ontario, and less along the shores of Lakes Erie and Ontario than in Muskoka. Con- versely, when the winds are from the southwest hot dry air from the midwest- ern States will move northward to the shores of Hudson Bay, frequently reports temperatures in the nineties in mid-sum- mer, which may be followed in a few hours by snow, if the wind shifts abruptly to the north. The height of land, between the Great Lakes and Hudson Bay, lies only a very short distance north of Lake Superiof. The highest hills in Ontario rise abruptly to the watershed just north of the lake beyond which the land slopes gently south- ward for several hundred miles to the level shores of Hudson Bay and James Bay. The watershed extends eastward from Lake Superior through the Kirkland Lake vicinity. Compression of air as it moves downhill tends to make it warmer and drier and expansion of air as it moves uphill causes cooling and condensation. Consequently terrain effects in summer accentuate the coolness and high humidity of air moving into northern Ontario from the north and likewise augment the warmth and dryness: of air from the south. The area around North Bay, Sudbury' and Haileybury will have more sunshine and temperatures about ten degrees higher. than the Timmins-Kapuskasing region
