Anvil Clouds of Tropical Mesoscale Convective Systems in Monsoon Regions
Feb 26, 2010 [ Research Highlights ]
In the tropics, upper-level clouds containing ice and mixtures of ice and liquid water strongly affect the transfer of radiation through the atmosphere. A large proportion of these clouds are associated with deep convection, which generates and lifts hydrometeors to upper levels. Systems of deep convection that are larger than ~100 km in dimension [...]

Detangling Convective Oscillations at ARM Tropical Western Pacific Site: Manus
Jan 25, 2010 [ Research Highlights ]
Observed tropical convections are typically organized as intraseasonal oscillations (about 30-80 day periods) throughout the equatorial zone, the so-called Madden-Julian Oscillation (MJO). The most common feature of the MJO is that it weakens over the Maritime Continent and grows back to about full strength towards the Tropical Western Pacific (TWP), and then propagates to the [...]
