'Aufsteigend' is the present participle of the verb 'aufsteigen' (to ascend/rise). It is used like a normal adjective and is declined before a noun. The basic meaning is always 'moving upward.'

In its literal meaning, 'aufsteigend' (ascending/rising) often describes physical phenomena. Typical nouns are 'aufsteigender Rauch' (rising smoke), 'aufsteigende Wärme' (rising heat), or 'aufsteigender Nebel' (rising fog).
Vorsicht, der aufsteigende Dampf aus dem Topf ist sehr heiß.
Careful, the rising steam from the pot is very hot.
In the context of lists and data, 'aufsteigend' (ascending) is often used as an adverb with verbs like 'sortieren' (to sort) or 'ordnen' (to arrange). It then serves as an instruction for how something should be ordered.

'zunehmend' and 'aufsteigend' can both make you think of upward movement. However, 'zunehmend' usually describes quantity, intensity, or frequency becoming greater. So it is about a development. 'aufsteigend' more often describes an upward direction or an order from low to high, for example with numbers, prices, or names. The words can be confused when talking about values. If something is becoming more and more, 'zunehmend' fits. If something is ordered by height, size, or sequence, 'aufsteigend' fits.
