Rough and Irregular Ice Crystals in Mid-latitude Clouds

1. INTRODUCTION Cloud feedbacks are the largest source of uncertainty in climate models. In particular, uncertainties exist concerning the radiative forcing of clouds containing ice crystals, most notably cirrus. Indeed, whether cirrus clouds warm or cool the Earth's surface depends on ice crystal morphology. Reducing this uncertainty requires detailed in situ characterization of cloud particle...

Surface Source of Ice Particles in Mountain Clouds

This paper focuses on wintertime orographic clouds not associated with major synoptic disturbances, but formed by strong winds across major barriers. Such clouds constitute a major source of precipitation in many regions of the world and are frequent targets of cloud seeding activities aimed at increasing the mountain snowpack. For these reasons such clouds have been extensively observed and mo...

Ice Concentration Retrieval in Stratiform Mixed-Phase Clouds Using Cloud Radar Reflectivity Measurements and 1-D Ice-Growth Model Simulations

Lenticular wave clouds are used as a natural laboratory to estimate the linear and mass growth rates of ice particles at temperatures from 2208 to 2328C and to characterize the apparent rate of ice nucleation at water saturation at a nearly constant temperature. Data are acquired from 139 liquid cloud penetrations flown approximately along or against the wind direction. A mean linear ice growth...
