Martinez et al. (2022) analyzed temperature data of Jupiter’s upper atmosphere observed in 2018 and 2019. When superimposed on a map of Jupiter, time-lapse data representing several hours of observations from one day in 2018 and one day in 2019 indicate an overall temperature gradient from the poles to the equator, with highest temperatures occurring at the poles, which undergo auroral heating. But the 2019 data exhibit a large oval of unusually elevated temperature separated from the aurora at one pole by a band of cooler atmosphere. No other known heating mechanism on Jupiter could account for the formation of this anomalous structure, so one hypothesis considered was that it was ejected from the auroral region toward the equator.
Which finding about Jupiter’s upper atmosphere, if true, would most strongly support the hypothesis as described in the text?
AComparing the data observed in 2018 with those observed in 2019 suggests that the anomalous oval of elevated temperature began forming in 2018.
BThe 2019 data viewed in time-lapse show greater disparities between polar and equatorial temperatures at the beginning of the observation period than at the end of the period observed.
CAccording to the data, auroral temperatures in 2018 were higher than those in 2019, although in both years the highest observed temperatures were harbored in auroral zones.
DThe 2019 data viewed in time-lapse appear to show the oval of elevated temperature drifting slightly away from the area of auroral heating over a period of several hours.
