Question

What causes equable climate ? Explain in brief . (Plzz ans this question).

Answer 1

In a one sentence explanation, equable climates are periods of roughly equal temperatures throughout the world. A more detailed description focuses on the equator to pole temperature difference (EPTD) and the seasonality in the high-latitudes, or regions that are above 60°N or below 60°S. The equator to pole temperature difference describes exactly what it sounds like: the difference in temperature between the region near the equator and the areas close to the poles. Presently, there is a large difference between the two regions' temperatures; however, this situation has not always existed. During the late Cretaceous period (~100 to 65.5 million years ago) and the early Paleogene period (65.5 to 34 million years ago), the poles were much warmer than they are currently and were much closer to equatorial temperatures than they are today. Additionally, the temperatures in the high-latitudes did not fluctuate as much as they do today, and in the winter, they remained closer to summer temperatures than they do now. This behavior can be termed low seasonality. Combining these characteristics defines equable climates. They are periods with a low EPTD and low seasonality.
