Figure 1 shows the average diurnal variation of ozone and total peroxide in baseline air for January 1992.

Because of the aridity, there tends be considerable diurnal variation in temperature, except during the summer.

The colonoscopies were carried out between 1100 and 1300 to allow for diurnal variation in proliferation rates.

This is high enough to permit observation if the diurnal variation.

Each had classic symptoms, including what is called diurnal variation of mood: depressed patients typically feel worse in the morning and get better toward evening.

Elicit the temporal features including onset, duration, and diurnal variation.

Annual temperature variations are small, although diurnal variations can be extreme.

Temperatures are cooler and subject to less annual and diurnal variation than in other regions.

Astronomical observations near the Earth's poles can be done over long periods, without the diurnal variations at lower latitudes.

The marsh is subject to diurnal tidal variations of approximately 5.5 feet (1.7 m).
