The spatial organization and time dependence of Jupiter's stratospheric temperatures have been measured by observing thermal emission from the 7.8-micrometer CH(4) band. These temperatures, observed through the greater part of a Jovian year, exhibit the influence of seasonal radiative forcing. Distinct bands of high temperature are located at the poles and mid-latitudes, while the equator alternates between warm and cold with a period of approximately 4 years. Substantial longitudinal variability is often observed within the warm mid-latitude bands, and occasionally elsewhere on the planet. This variability includes small, localized structures, as well as large-scale waves with wavelengths longer than approximately 30,000 kilometers. The amplitudes of the waves vary on a time scale of approximately 1 month; structures on a smaller scale may have lifetimes of only days. Waves observed in 1985, 1987, and 1988 propagated with group velocities less than +/-30 meters per second.
通过观测 7.8 微米 CH(4) 带的热辐射，测量了木星平流层温度的空间组织和时间依赖性。这些在木星年的大部分时间内观测到的温度，表现出季节性辐射强迫的影响。高温带明显位于极地和中纬度地区，而赤道则在大约 4 年的时间内经历冷暖交替。在温暖的中纬度带内，经常观察到大量的纵向可变性，在行星的其他地方偶尔也会观察到。这种可变性包括小的局部结构，以及波长大于约 30000 公里的大尺度波。波的幅度在大约 1 个月的时间尺度上变化；较小尺度上的结构寿命可能只有几天。在 1985 年、1987 年和 1988 年观测到的波以小于正负 30 米/秒的群速度传播。
