Explanation:

Both statements are correct.

During the positive phase of the PDO, the sea surface temperatures in the central and eastern Pacific are warmer than average, while the western Pacific tends to be cooler than average. A ‘warm’ phase of PDO occurred from 1977 to 1999 (22 years). This warmer-than-normal condition can lead to various effects on weather and climate, such as:

Increased likelihood of wetter and cooler conditions along the western coast of North America.
Warmer and drier conditions in the western Pacific, including Australia and parts of Asia.
Altered atmospheric circulation patterns, affecting storm tracks and precipitation patterns.
During the negative phase of the PDO, the sea surface temperatures in the central and eastern Pacific are cooler than average, while the western Pacific is relatively warmer than average. A ‘cool’ phase of PDO occurred from 1947 to 1976 (29 years). This phase also has significant impacts on weather and climate:
Increased likelihood of drier and warmer conditions along the western coast of North America.
Cooler and wetter conditions in the western Pacific, affecting regions like Australia and parts of Asia.
