The phrase "and occurrence of rainfall" is correct and usable in written English.
It can be used when discussing weather patterns, climate studies, or environmental reports where rainfall is a relevant factor.
Example: "The study focused on the temperature variations and occurrence of rainfall in the region over the past decade."
Alternatives: "and instances of rain" or "and frequency of precipitation".
DFA results showed that groundwater concentration of three of the agrochemical species studied (N NO3−, P PO43−and Total P) were affected by the same explanatory variables (water table depth, enriched topsoil, and occurrence of a leaching rainfall event, in order of decreasing relative importance).
All these areas are within high and very high hazard zones and are dominated by low slope, significant occurrence of rainfall, tertiary sand, ferralitic soil strongly desaturated and low drainage within the Abidjan district.
It plays a significant role in the formation, occurrence of rainfall, and groundwater reservoir that are replenished through infiltration.
Especially, the precedent procedures consist of the building of the database, DEM construction, and determination of susceptibility value and vulnerability value in order to consider the overall debris flow potential in the target area, prior to the occurrence of rainfall and debris flow.
Choice of material takes into account amount of rainfall, climate, and occurrence of temperatures below freezing.
After the occurrence of rainfall events, the volume of percolated water in lysimeters and the sediment and water losses in plots was measured.
H.C. Peirera, then one of the world's renowned hydrologists, wrote in his 1973 book on water in temperate and climate regions: "There is no corresponding evidence as to any effects of forests on the occurrence of rainfall" (cited from Hamilton 1992).
This observation needs to be investigated further because it is contrary to the thinking that southern Africa is likely to get drier due to climate change and consequently has high occurrences of rainfall extreme events (Lioubimtseva and Henebry [2009]; Eriksen and Silva [2009]).
If the occurrence of rainfalls at different rain gauges within a given concurrent period is similar (e.g. high correlation of the numbers of rainy hours within a given one-day interval), these gauges are thus considered as members of a homogeneous group.
