WebThe annual component of the change of the length of day of Δτ ≈ 0.34 ms corresponds then to a superrotation of u ≈ 0.9 m/s, and the semiannual component of Δτ ≈ 0.29 ms to u ≈ 0.8 m/s. See also [ edit] Atmospheric super-rotation References [ edit] ^ Hide, R. (1989). WebUsing Eq. (6), local time is 0830+4 (60–63 degrees)=0818. Table 1 gives the ET as −7 min, so AST=0818 – 7=0811 or 229 min from local solar noon; therefore, the hour angle, H =0.25×229 min=57.3 degrees. As calculated in Example 10 and also provided in Table 1, the solar declination on March 21 is 0 degree.
