The phrase "a sharp gradient" is correct and usable in written English.
It can be used to describe a steep or significant change in a particular variable, often in contexts like mathematics, physics, or geography.
Example: "The landscape features a sharp gradient, making it challenging for hikers to navigate the terrain."
Alternatives: "a steep gradient" or "a steep slope".
There was a sharp gradient between high rainfall totals in western Scotland and Snowdonia, where rainfall was above average, and dry conditions across parts of southern England.
Within the stress transfer zone there is a sharp gradient in the shear strain.
If only a sharp gradient of conductivities is considered, the terminator effects are almost the same at dawn and dusk.
Therefore, the vorticity creation zone does not profit from the reaction neighbourhood promoting a sharp gradient of density.
The geographic distribution of the amplitude of periodic signals is essentially zonal in geomagnetic coordinates, presenting a sharp gradient in the auroral zone.
Under these circumstances, a sharp gradient principally can arise and an effective concentration of a secreted morphogen will reach its related receptor [73].
The lack of any sharp gradient of genetic diversity between East Asian and African village dogs could mean that once domesticated, dogs spread very quickly from their point of origin.
The k profiles show the same trend as Figure 15 albeit with a positive sharp gradient in the region 0.4≤ z/h b ≥ 0.6.
This represents a novel strategy for the strength-ductility improvement which emphasizes the importance of work hardening and thickness of gradient layer (not a narrow sharp gradient) in material design.
The possibility remains that this sharp gradient is an artifact caused by atmospheric disturbance.
For nonlinear hyperbolic equations, weighted essentially non-oscillatory (WENO) methods are a class of schemes with a uniformly high order of accuracy in smooth regions of the solution, which can also resolve the sharp gradient in an accurate and essentially non-oscillatory fashion.
