The applied science that examines the interactions between meteorological, hydrological and pedological factors on one hand and directly addresses the most critical factor governing agriculture, horticulture, animal husbandry and forestry on the other. It is increasingly recognized as one of the most important and future-oriented branches of agricultural science. 

What sets agromet apart?The discipline is not merely meteorology applied to farms. It is a fundamentally cross-disciplinary framework drawing one urgent question: how do we feed humanity when the sky itself is becoming unpredictable? Conventional agricultural sciences treat the climate as a background constant. Agronomy depends on weather for crop growth, horticulture on chilling accumulation, frost occurrence; soil science is closely linked with soil moisture dynamics, evapotranspiration and rainfall distribution; entomology and plant pathology rely heavily on temperature and humidity for pest and disease forecasting. Even agricultural economics models yield-price relationships without internalising the stochasticity of rainfall or temperature. Agromet, hence, serves as the “central nervous system” of agriculture because agriculture is entirely dependent on atmospheric conditions and every agricultural activity including sowing, irrigation, fertilizer application, pest management, harvesting and post-harvest operations is influenced by weather variability. The discipline now integrates remote sensing, GIS, artificial intelligence, machine learning, drones, satellite meteorology, crop simulation models, automatic weather stations and IoT-based sensors. Such innovations have transformed agriculture from a conventional practice into precision and climate-smart farming. Today, real-time weather advisories, drought alerts, irrigation scheduling, and disease forecasting systems are increasingly helping farmers minimize losses and improve productivity. Therefore, agrometeorology is not only a science of observation but also a science of prediction, preparedness and adaptation. 

Vulnerability of hill agriculture: The importance of agrometeorology becomes even more pronounced in the Himalayan and hilly regions of India. The Himalayan, Western Ghats, and Northeastern hill zones represent a distinct and acutely vulnerable agro-climatic frontier. Rising temperatures, declining snowfall, glacial retreat, cloudbursts, droughts, landslides, flash floods and erratic precipitation patterns are increasingly affecting agriculture and livelihoods across the region. In temperate areas such as Kashmir Valley, slight changes in winter temperature can significantly alter chilling hour accumulation required for apple, walnut, almond and cherry cultivation. Variability in precipitation also affects saffron production, irrigation availability and water resource sustainability. Snowline retreat in Himachal Pradesh and Uttarakhand has pushed traditional apple-growing belts upward by 200-500 metres over four decades. Potato cultivation in Spiti and Lahaul, staple to food security at 3,500 metres, now faces erratic frost dates that collapses carefully planned crop calendars. Cardamom in the Sikkim hills has suffered yield losses exceeding 30% due to cloud cover shifts and altered rainfall intensity. Therefore, weather-based scientific management becomes essential for maintaining agricultural........
