Superstrong photospheric magnetic fields in sunspot penumbrae
Context. Recently, there have been some reports of unusually strong photospheric magnetic fields (which can reach values of over 7 kG) inferred from Hinode SOT/SP sunspot...- publication PDF

Mechanisms for precipitation enhancement in a North American monsoon...
Tropical upper-tropospheric troughs (TUTTs), transient summertime disturbances over the Pacific and Atlantic Oceans, are also observed to frequently occur in the North American...- publication PDF

Response of the thermosphere and ionosphere to an ultra fast Kelvin wave
Ultra Fast Kelvin (UFK) waves are eastward propagating planetary waves with periods between 3 and 5 days, which are capable of penetrating into the thermosphere and ionosphere...- publication PDF
