"occurrence peak" is a correct and usable phrase in written English.
It can refer to the highest point or peak of a certain event or phenomenon. It is typically used in scientific or technical contexts. Example: The study showed that the occurrence peak of the virus was in the winter months, with a significant decrease in cases during the summer.
There was higher prevalence in male (4:1), with occurrence peak between 20 to 29 years old.
During June solstice the occurrence rate is lower than during the other seasons; an occurrence peak exists around Africa.
In the statistical study by Rietveld et al. (1996), NEIAL were typically observed in the F region with an occurrence peak around 500 km altitude and no cases below 300 km altitude with both ion-acoustic shoulders enhanced simultaneously were found.
These results with post-sunset equatorial irregularities whose occurrence peak falls on the equinox and lowest values during solstices are in a proper agreement with climatological characteristics of the plasma bubbles occurrence in the topside ionosphere reported in previous studies (e.g., Burke et al. 2004; Su et al. 2006; Stolle et al. 2006; Park et al. 2013).
As cases associated with this type of scrub typhus occurred from September to December with an occurrence peak in October, it was called "autumn-winter type".
This type of scrub typhus emerged in 1986 in northern China and occurred exclusively from September to December with an occurrence peak in October, which was different from the summer type endemic in southern China.
This hypothesis is studied by testing the significance of temporal clustering in flood occurrence (peak-over-threshold) time series for 68 catchments across Germany for the period 1932 2005.
In Fig. 4b, the substorm occurrence peaks around 1994 and 2003 2004, and decreases gradually until 2002 and 2014.
Concerning especially Pc5 pulsations (periods 150 600 s), their latitudinal occurrence peaks around 70 degrees (Baker et al., 2003).
In contrast, the occurrence peaks significantly higher just after the ICME impact but drops to background levels 1 or 2 days after the ICME arrivals.
The global morphology of ionospheric scintillation occurrence is well known (Basu et al. 2002; Liu et al. 2016) with occurrence peaks at auroral to polar latitudes (65° 90° geomagnetic latitudes) and the equatorial bands (extending from 20°N to 20°S geomagnetic latitudes).
