- Location: The peninsular plateau is located between 15°N and 23°N latitudes whereas the northern plains lie between 23°N and 35°N latitudes. The peninsular plateau is closer to the equator and therefore receives more direct sunlight throughout the year. As a result, the temperatures are higher in the peninsular plateau than in the northern plains.

- Altitude: The peninsular plateau is higher in altitude than the northern plains. The average altitude of the peninsular plateau is 600 meters above sea level, while the average altitude of the northern plains is 100 meters above sea level. As altitude increases, the temperature decreases. Therefore, the peninsular plateau experiences lower temperatures than the northern plains.

- Rainfall: The peninsular plateau receives more rainfall than the northern plains. The average annual rainfall in the peninsular plateau is 1000 mm, while the average annual rainfall in the northern plains is 700 mm. Rainfall helps to cool the air and reduce the temperature. Therefore, the peninsular plateau experiences lower temperatures than the northern plains.

- Wind patterns: The peninsular plateau is affected by the monsoon winds, which bring moisture from the Bay of Bengal. The monsoon winds blow from the southwest from June to September and from the northeast from October to May. The monsoon winds bring rainfall and help to cool the air. Therefore, the peninsular plateau experiences lower temperatures than the northern plains.

- Vegetation: The peninsular plateau has more vegetation than the northern plains. Forests help to cool the air and reduce the temperature. Therefore, the peninsular plateau experiences lower temperatures than the northern plains.
