What aspect characterizes exposure to both summer and winter winds for a west-facing slope?

The correct choice highlights the significant impact of solar radiation on the west-facing slope, particularly during the summer months. West-facing slopes receive intense sunlight in the afternoon, which leads to hotter temperatures in this segment of the day compared to other orientations. The heat generated from the afternoon sun can create thermal updrafts and influence local weather patterns, which plays a crucial role in understanding exposure to seasonal winds.

While the dominant feature of a west-facing slope during summer is indeed the hot afternoon sun, it is important to note that this characteristic does not negate the slopes' exposure to winter winds. In fact, these slopes also experience the effects of cold winter winds but not to the extent of overshadowing the significance of the solar exposure. The choice regarding direct morning sunlight primarily pertains to east-facing slopes, which receive morning light instead. Saying there is no wind exposure is inaccurate as these slopes can experience both summer and winter winds. Thus, the correct choice effectively encapsulates the primary condition that defines the summer characteristics of a west-facing slope.
