The phrase "altitude gradient" is correct and usable in written English.
It can be used in contexts related to geography, meteorology, or aviation, where changes in altitude are being discussed.
Example: "The altitude gradient in this region affects the climate and vegetation significantly."
Alternatives: "elevation change" or "height gradient".
Xie, X. et al. Landscape pattern change in mountainous areas along an altitude gradient in the upper reaches of Shule River.
This study presents an analysis of leave and rood morphology, biochemical and proteomics approach as adaptation strategies of the alpine plant Potentilla saundersiana in an altitude gradient.
The recharge elevations of the individual springs were calculated from their δ18O-values and the equation of the altitude gradient (−0.16‰ δ18O/100 m) of precipitation on the mountain.
The loss of traditional herding systems that regulated selective management of fragile grazing grounds along the altitude gradient in the HPA, particularly for camels, the overexploitation of woody perennials for construction purposes, and the resettlement of former migrant workers are major constraints for the successful implementation of the government-designed management plan.
Five samples were tested repeatedly at each altitude gradient.
Spruce and birch are more evenly distributed across the altitude gradient than pine.
With an altitudinal range of 5000 m a.s.l., spiny frogs provide one of the broadest altitude gradients in the world for analyzing altitudinal patterns of species diversity.
A negative stable isotope-altitude gradient is commonly observed on the windward side of a mountain.
The effect of moisture recycling is more significant than that of sub-cloud evaporation on the leeward side of the Tianshan Mountains; therefore, the precipitation in the Tianshan Mountains has a positive δ18O-altitude gradient.
Accordingly, we concluded that the stable isotope-altitude gradient on the leeward side of a mountain is very sensitive to local atmospheric processes; an inference that should be taken into consideration while quantifying the paleo-altitude of orogeny and groundwater recharge area using stable water isotopes.
The model showed that the δ18O-altitude gradient rises by 0.28‰/100 m with the difference of the recycled fraction increasing by 1%/100 m, and declining by 0.15‰/100 m with the difference of the evaporated fraction increasing by 1%/100 m.
