F18 GAVA (x 10-9 s-2) positive at F24 position

3.0 x 10-9 s-2
4
F18 nearly LTHAD (x 10-13 m-1s-1) positive at
F24 position

-9.81 m s-2/ (11.72x10-5 s-1)(2.1x10-13
m-1s-1) -17.58 x 10-9 s-2
So, multiply by g/f, giving a negative LTHAD
contribution to cyclolysis
5
F18 nearly 850 hPa LAD (x 10-13 units) positive
at F24 position

17.58 x 10-9 s-2 85 -14.94 x 10-9 s-2
So, multiply by g/f, giving a negative LAD
contribution to cyclogenesis
6
F18 nearly 700 hPa LAD (x 10-13 units) negative
at F24 position

17.58 x 10-9 s-2 85 14.94 x 10-9 s-2
So, multiply by g/f, giving a positive LAD
contribution to cyclogenesis
