WeatherArb calculates Z-Score, HDD and CDD against the NASA POWER 25-year baseline for Merta (26.65°N, 74.03°E). EN ISO 15927 standard.
Merta is located in the northwestern state of Rajasthan, India. It falls within the semi-arid climate zone characterized by hot summers and relatively dry conditions for much of the year. The region experiences significant temperature variations between seasons, typical of interior desert and steppe climates found across western India.
Summer temperatures in Merta often climb above 40 degrees Celsius between April and June. Winters from December to February bring much cooler conditions, with nighttime lows sometimes dropping near 5 degrees Celsius. The annual temperature range is substantial, reflecting the continental influence far from moderating coastal effects.
The monsoon season arrives in Merta around July and continues through September. Rainfall remains moderate and somewhat erratic due to the semi-arid classification, with the southwest monsoon bringing most of the annual precipitation. These months offer temporary relief from the intense summer heat before dry conditions return.
Cos'è lo Z-Score climatico?
Misura quante deviazioni standard la temperatura attuale di Merta 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 Merta?
WeatherArb aggiorna i dati meteo di Merta ogni ora tramite MET Norway, NOAA NWS e WeatherAPI.
Weather Merta Today — Temperature and Climate Anomalies
WeatherArb monitors current temperature in Merta 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 Merta 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 Merta — Moderate Seismic Risk
Merta is with significant regional seismic hazard, particularly in the Himalayan region (north) and Andaman Islands, where the Indian plate collides with the Eurasian plate. 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.
