The phrase "a clear velocity" is correct and usable in written English.
It can be used in contexts where you want to describe a specific and easily understandable speed or rate of movement.
Example: "The car maintained a clear velocity throughout the race, allowing the driver to navigate the curves with precision."
Alternatives: "a distinct speed" or "an evident rate".
During 1750 1830 JST there appear clear velocity oscillations with a maximum peak-to-peak amplitude of 60 m/s at ranges of 500 800 km and with a maximum peak-to-peak amplitude of 30 m/s at ranges of 800 1000 km.
Also the clear velocity gradient across the Ushikubi fault is restricted to the central part of the fault (Fig. 7).
As also found by Nishitani et al. (2011), the horizontal propagation velocities exhibited clear velocity dispersion, that is, changed from 6.7 to 1.8 km/s with time.
A high-resolution velocity image along a profile that crosses the cluster area depicts a clear high-velocity (Vp > 6.0 km/s) crustal body around a depth of 5.0 km (Karabulut et al., 2003).
Seismic tomography investigations indicated a clear low-velocity zone beneath this region (e.g., Nakajima and Hasegawa, 2007), (2008).
The velocity waveform was recorded from the midstream of the vessel lumen and the sample volume was adjusted to cover the center of the arterial vessel, in order to obtain a clear Doppler blood velocity trace.
Almost annual change in relative velocity changes is clearly found in both of the estimated seismic velocity changes and geodetic signals from GNSS receivers, which is a clear example that seismic velocity is well correlated with geodetic signals at a volcano.
A clear P-wave low-velocity layer is visible at the lower plane of the double seismic zone.
Even though the changes during the first 3 days were small, there was a clear trend of increasing velocities throughout the study period.
Comparison of results for LV flow with two valve models demonstrated a clear distinction between pressure distribution, velocity distribution, vortex formation/growth/vanishing and energy dissipation especially in the filling phase.
