What Wikipedia says

In meteorology, the polar highs are areas of high atmospheric pressure, sometimes similar to anticyclones, around the North and South Poles; the south polar high (Antarctic high) being the stronger one because land gains and loses heat more effectively than sea, which the north has much less of.
