A campus weather station reports temperature, relative humidity, and pressure every minute. Over one week in late spring, the station records a daily temperature cycle peaking near 15:00 and a slow pressure fall of about 6 hPa over three days, followed by a wind shift from south to northwest and a 9 °C temperature drop within six hours.
