WeatherArb calculates Z-Score, HDD and CDD against the NASA POWER 25-year baseline for Hitachi-Naka (36.40°N, 140.53°E). EN ISO 15927 standard.
Cos'è lo Z-Score climatico?
Misura quante deviazioni standard la temperatura attuale di Hitachi-Naka 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 Hitachi-Naka?
WeatherArb aggiorna i dati meteo di Hitachi-Naka ogni ora tramite MET Norway, NOAA NWS e WeatherAPI.
Weather Hitachi-Naka Today — Temperature and Climate Anomalies
WeatherArb monitors current temperature in Hitachi-Naka 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 Hitachi-Naka are updated hourly. During heatwave conditions (July: elevated heat anomaly risk), the anomaly level rises to EXTREME or CRITICAL — a statistically rare climate event.
Seismic Risk Hitachi-Naka — High Seismic Risk
Hitachi-Naka is one of the world's most seismically active countries, with thousands of earthquakes per year. Located at the junction of four tectonic plates (Pacific, Eurasian, North American, Philippine). WeatherArb integrates real-time climate anomaly monitoring with USGS seismic data to provide a comprehensive view of natural risk factors affecting agriculture, infrastructure and public safety.
