The phrase "a temperature fluctuation from" is correct and usable in written English.
You can use it when discussing changes in temperature, particularly in scientific or technical contexts.
Example: "The experiment showed a temperature fluctuation from 20°C to 25°C over the course of an hour."
Alternatives: "a temperature variation from" or "a temperature change from".
To test PCR amplification using the thermally baffled device under different environmental temperature fluctuation from room temperature to 45°C (28°C, 38°C, or 45°C, respectively) or the windy conditions, we used a plasmid containing a sequence specific to YHV as the template to amplify a specific 67-bp fragment.
The result was a decadal (10-year) forecast of global temperature fluctuations from 2005 that indicated that warming might be subdued for several years by internal variability but that the climate would continue to warm, so the average global temperature in at least one-half of the years from 2010 to 2014 would exceed that of the warmest year on record, 1998.
Annual data would be even better but temperature fluctuations from year to year are too small to produce significant variation in death rates.
"In the summer, extreme temperature fluctuations from hot to cold cause moisture to build up, and sometimes the hardwood pellets and charcoal get wet from condensation — especially if the grill is in the sun," he says.
Here we present changes of the meridional wind jet in comparison with temperature fluctuations from August 2004 to May 2006 at time scales of 11 30 days.
There are high annual and daily temperature fluctuations from − 53 °C in January to 42 °C in July, countrywide (Marin 2010).
River water and to some extent lake water undergoes big temperature fluctuations, from freezing point up to 25°C in summer.
Movement along rural country roads and temperature fluctuations from -5°C to over 40°C can affect the stability of detectors and lasers.
Temperature fluctuations from the light source we not observed during irradiation cycling, and a temperature versus time plot included in Figure 5 shows a nearly isothermal process over this time frame.
Remani et al. (1983) and Chandran and Ramamoorthi (1984) mentioned that the temperature fluctuation was a seasonal phenomenon resulting from the monsoonal effect.
