The north-south temperature gradient refers to the change in temperature with latitude. This gradient is much steeper in winter than in summer. In winter, the high latitudes receive very little or no solar radiation, leading to very cold temperatures, while the low latitudes remain relatively warm. This creates a large temperature contrast. In summer, high latitudes receive much more solar radiation (long daylight hours), warming them significantly, which reduces the temperature difference between high and low latitudes, making the gradient less steep.
