The meteorological tephigram is explained briefly, with emphasis on the aesthetic appeal it offers to an observer informed via cloud photography. This tephigram refers to clouds shown on the main page.
The trace of the Temperature of the atmosphere, on the right, shows an approximate match with that for the moisture content of the air, represented by the Dew Point Temperature, on the left. Increase in energy is signalled if Temperature rises; also if the Dew Point Temperature rises. On tephigrams the two traces commonly move in opposed directions. If Temperature is increased then usually Dew Point Temperature is decreased: a balance is indicated: Warmth often accompanies dryness; coldness often accompanies increased moisture content. [An account of the distincive clouds shown in the Frontispiece of my main page was published in Weather, 58, pp 84-9, Feb 2003, along with an appropriate discussion of a tephigram representative of its circumstances.]
The tephigram e30tef6 shown above is pleasing to the eye of an enthusiast: Note how the layer near the surface - up to ~870 hPa - is well mixed, and that the lowest 20 hPa, the lowest 200 m in altitude, is slightly different in character. It features a dry adiabatic lapse rate of Temperature. The Temperature trace leans to the left at the dry adiabatic Temperature lapse rate, 9.8°/km. From about 970 hPa up to the 880 hPa level the lapse rate is ~6.5°/km; this is the usual, recognized, moist adiabatic lapse rate for our tropical oceans. Convective mixing leads to this lapse rate: there were many clouds fulfilling their role of getting the received solar heat off the surface.
There is a disparity between the examination for Answer 31 in which a stable layer capable of yielding waves has been inferred, and the paragraph above in which no such singularity has been noticed. However there are minor wiggles, and I infer that these do represent real disturbances.
A marked temperature inversion at pressure 750 hPa is obvious. This is usual during the Winter monsoon. It results from subsidence of the whole upper air mass (at very roughly the speed a human baby could crawl). The tephigram features an inversion at 925 hPa, and it features air masses of apparently different character superimposed, worthy of close attention should one want to infer what had been happening. .
