RISCirrus, Transport, and Mixing in the Tropical Upper Troposphere
Publisher: American Meteorological Society
Abstract: he impact of cloud radiative heating on transport time scales from the tropical upper troposphere to the stratosphere is studied in two-dimensional numerical simulations. Clouds are idealized as sources of radiative heating ...
Large Internal Variability Dominates over Global Warming Signal in Observed Lower Stratospheric QBO Amplitude

Vertical Mixing and the Temperature and Wind Structure of the Tropical Tropopause Layer
Publisher: American Meteorological Society
Abstract: ertical mixing may lead to significant momentum and heat fluxes in the tropical tropopause layer (TTL) and these momentum and heat fluxes can force large climatological temperature and zonal wind changes in the TTL. The ...
Cloud and Radiative Balance Changes in Response to ENSO in Observations and Models
Publisher: American Meteorological Society
Abstract: he authors use observations and four GFDL AGCMs to analyze the relation between variations in spatial patterns and area-averaged quantities in the top-of-the-atmosphere radiative fluxes, cloud amount, and precipitation ...

Impacts of Atmospheric Temperature Trends on Tropical Cyclone Activity
Publisher: American Meteorological Society
Abstract: mpacts of tropical temperature changes in the upper troposphere (UT) and the tropical tropopause layer (TTL) on tropical cyclone (TC) activity are explored. UT and lower TTL cooling both lead to an overall increase in ...
Seasonal Prediction Skill of Northern Extratropical Surface Temperature Driven by the Stratosphere
Publisher: American Meteorological Society
Abstract: AbstractThis study explores the role of the stratosphere as a source of seasonal predictability of surface climate over Northern Hemisphere extratropics both in the observations and climate model predictions. A suite of ...
