Krishnamurti's dataset provides 100 days of tropical wind analyses for the 300mb, 250mb, and 200mb atmospheric levels. The analyses contain u- and v-components of wind on a 2.5-degree grid covering the tropical globe and were provided by T.N. Krishnamurti at Florida State University. The data was last updated in 1974.
Use Cases
- Analyzing temporal patterns of wind speed and direction at the 300mb, 250mb, and 200mb levels over 100 days.
- Mapping spatial wind vector fields across the tropical globe using the gridded u- and v-components.
- Comparing historical upper-level wind conditions from 1974 with contemporary atmospheric data.
- Studying the vertical structure of tropical winds across three specified pressure levels (300mb, 250mb, 200mb).
Strengths
- Contains 100 days of continuous wind data for analysis.
- Provides wind data at three distinct atmospheric levels (300mb, 250mb, 200mb).
- Offers spatially complete coverage of the tropical globe on a 2.5-degree grid.
Limitations
- Data is temporally limited to a specific historical period (1974).
- The 2.5-degree grid resolution may be coarse for studying localized phenomena.
- Sample size (number of rows/records) is unknown, potentially limiting statistical analysis.
