Metainformaçao

COLD WAVE: &nbsp; Indicator that represents the number of days, at intervals of at least 6 consecutive days, which daily minimum temperature is 5 °C below the average daily value in the reference period.
REFERENCE PERIOD: &nbsp; Period to which the information refers and which may be a specific day or a time interval (month, fiscal year, calendar year, among others).
WEATHER STATION: &nbsp; Facility where scientific studies are conducted and atmospheric phenomena are observed for the purpose of making weatherforecasts. Information gathered by weather stations and satellites is collated by computers at central departments and mathematical models.
