Se presenta un modelo unidimensional para representar la difusión térmica vertical nocturna en la capa límite atmosférica marina y diagnosticar inversiones de temperatura de interés operacional. El objetivo fue evaluar la respuesta del sistema ante cuatro escenarios sintéticos de contraste aire–mar y viento mediante una ecuación parabólica de difusión con difusividad turbulenta dependiente de estabilidad, condición de borde de flujo sensible y enfriamiento radiativo constante. El problema se resolvió con Crank-Nicolson en una columna de 600 m durante 6 h. Los resultados muestran que los casos con mar más frío y viento débil desarrollan inversiones más intensas, mientras que el escenario control con mar más cálido no supera el umbral diagnóstico. La intensidad integrada máxima se obtuvo en E3. Se concluye que el esquema reproduce de forma consistente la transición entre regímenes con y sin inversión y constituye una base trazable para validación futura.
