Cos'è lo Z-Score climatico?
Misura quante deviazioni standard la temperatura attuale di Utrecht si allontana dalla media storica dello stesso mese. Sopra +2σ indica caldo anomalo raro; sotto -2σ indica freddo anomalo.
Cosa sono HDD e CDD?
Heating e Cooling Degree Days, standard EN ISO 15927, misurano la domanda energetica per riscaldamento/raffrescamento confrontando la temperatura con una soglia di 18°C.
Con quale frequenza si aggiornano i dati di Utrecht?
WeatherArb aggiorna i dati meteo di Utrecht ogni ora tramite MET Norway, NOAA NWS e WeatherAPI.
Weather Utrecht Today — Temperature and Climate Anomalies
WeatherArb monitors current temperature in Utrecht against the NASA POWER 25-year climate baseline. When an extreme heat event, unusual rainfall or cold snap occurs, the Z-Score is automatically updated.
Humidity, wind speed and feels-like temperature in Utrecht are updated hourly. During heatwave conditions (July: elevated heat anomaly risk), the anomaly level rises to EXTREME or CRITICAL — a statistically rare climate event.
