Description
Summary:This article analyzes the volcanic activity influences on temperature change in the tropical upper atmosphere (TUA) using sequential regression, case study and comparison. It is shown that the most volcano‐influenced area in air temperature is in the 70hPa layer of stratosphere at an altitude of about 22km; and the effect gradually decreases beyond or below the height, while the temperature increases in stratosphere but decreases in troposphere at 300hPa near the tropopause. Volcanic activity contributes 45.7% of total variance to the tropical temperature anomaly at 70hPa altitude. Case study on several volcanoes (i.e. Agung, Pinatubo, and El Chichon) of different intensities was conducted. As much as 80% of the temperature anomaly in the TUA would linger for 20 months. Therefore, volcanism is a strong factor causing temperature change in a long period after the explosion.
