Table 3. Correlation coefficients (R _xy ) at the 1% significance level (using Student’s t-test) between CAPE and rainfall data at the Delhi, Kolkata, and Trivandrum stations.

From: Influence of large-scale variations in convective available potential energy (CAPE) and solar cycle over temperature in the tropopause region at Delhi (28.3°N, 77.1°E), Kolkata (22.3°N, 88.2°E), Cochin (10°N, 77°E), and Trivandrum (8.5°N, 77.0°E) using radiosonde during 1980–2005
