WeatherArb calculates Z-Score, HDD and CDD against the NASA POWER 25-year baseline for Petworth (38.95°N, -77.02°E). EN ISO 15927 standard.
Cos'è lo Z-Score climatico?
Misura quante deviazioni standard la temperatura attuale di Petworth 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 Petworth?
WeatherArb aggiorna i dati meteo di Petworth ogni ora tramite MET Norway, NOAA NWS e WeatherAPI.
Weather Petworth Today — Temperature and Climate Anomalies
WeatherArb monitors current temperature in Petworth 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 Petworth 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 Petworth — Moderate Seismic Risk
Petworth is with high seismic activity concentrated on the West Coast (San Andreas Fault) and Alaska, while central and eastern states have lower risk. 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.
