31. The result is a wind which increases with altitude through the tropopause and upward to 100, 000 feet or above. 32. However, prior to 2000, increases in average Western Pacific SSTs had resulted in increases in tropopause cold point temperatures. 33. The tropopause is an inversion layer, where the air temperature ceases to decrease with height and remains constant through its thickness. 34. Due to the variation in starting height, the tropopause extremes are referred to as the equatorial tropopause and the polar tropopause. 35. Due to the variation in starting height, the tropopause extremes are referred to as the equatorial tropopause and the polar tropopause. 36. Due to the variation in starting height, the tropopause extremes are referred to as the equatorial tropopause and the polar tropopause . 37. Typically, radiative forcing is quantified at the tropopause in units of watts per square meter of the Earth's surface. 38. Where air density is significantly different, for instance because of temperature gradient, especially at the tropopause , CAT can occur. 39. This is why temperatures at the top of the troposphere ( known as the tropopause ) are about-50 degrees Celsius. 40. On comparatively rare occasions, convective lift can be powerful enough to penetrate the tropopause and push the cloud top into the stratosphere.
