WeatherArb calculates Z-Score, HDD and CDD against the NASA POWER 25-year baseline for Rongjiawan (29.15°N, 113.10°E). EN ISO 15927 standard.
Cos'è lo Z-Score climatico?
Misura quante deviazioni standard la temperatura attuale di Rongjiawan 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 Rongjiawan?
WeatherArb aggiorna i dati meteo di Rongjiawan ogni ora tramite MET Norway, NOAA NWS e WeatherAPI.
Weather Rongjiawan Today — Temperature and Climate Anomalies
WeatherArb monitors current temperature in Rongjiawan 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 Rongjiawan are updated hourly. During heatwave conditions (July: elevated heat anomaly risk), the anomaly level rises to EXTREME or CRITICAL — a statistically rare climate event.
