Thermodynamic Characterization of Wet and Dry Atmospheric States Using a Two-State Hidden Markov Model over the Middle Belt Region of Nigeria

I. O. Agada, V. Adah & O. Peter · Physical Science International Journal · 2026

Tropical temperature and rainfall variability in Nigeria is driven by interactions between thermal energy, latent and sensible heat fluxes, and large-scale circulation. Hidden Markov Models (HMMs) can link observed meteorological data to underlying thermodynamic regimes, providin...

Characterization of Rainfall Regimes in the Middle Belt States of Nigeria Using a 3-State Hidden Markov Model

I. O. Agada & V. Adah · Asian Journal of Physical and Chemical Sciences · 2026

This study applies a 3-state Hidden Markov Model (HMM) to 30 years daily rainfall data for the core seven Middle Belt states (Benue, Plateau, Niger, Kogi, Nasarawa, Kwara, FCT) in Nigeria with the aim of identifying underlying rainfall regimes. Rainfall in Nigeria exhibits consid...
