My BMW needs a new engine as a piston apparently punched through the base of the engine. Iâve been looking around for a second-hand one but am getting confused by engine model nos. My car is a V reg (1999) 318i SE E36 saloon shape. I canât work out if my engine is M44 or M43 (or something else!).
Because Antarctica is a polar region, there is no precipitation, it has no lakes or rivers and is in fact the driest continent. Average temperatures in the Antarctic interior get down to -70 degrees Celsius during the winter months and -35 degrees Celsius in the warmer months. The coastal temperatures are much warmer with a range of -15 to -32 Celsius in Winter and -5 to +5 Celsius in Summer. The interior of Antarctica is considered the world's driest desert because the extreme cold freezes water vapour out of the air.
But how cold can it get on Earthâs surface? What sort of weather brings on the record-breaking cold? On the high plateau of East Antarctica, there is a ridge along the ice sheet nearly 14,000 feet above sea level. The dry atmosphere and the long, sunless winter months combine to make this the coldest place on earth. Under the clear Antarctic night skies the snow surface radiates warmth into space, cooling the air just above the surface. As the air cools, it gets denser and starts to slide down the slope off of the ridge.
