Spectral distribution of cloud cover over Africa
| Orlanski, I., and L. J. Polinsky, 1977: Spectral distribution of cloud cover over Africa. Journal of the Meteorological Society of Japan, 55(5), 483-493. |
| Abstract: An analysis is made of the spectral characteristics of the cloud cover observed over Africa for a period of three months. The results indicate the predominance of a 2-2.7 day spectral peak within the vicinity of the Equator (10 degrees N - 10 degrees S) with the intensity of this peak much stronger over land than over the ocean. The peak itself may not be detected if the smallest resolved area used in the data analysis is too large. Coherence was found to be maximum in belt-like configurations along certain latitude bands. The phase difference, although very noisy, indicates a horizontal scale on the order of 2000 kilometers. |
