Midlatitude Tropopause and Low-level Moisture
A new relationship between the surface distribution of equivalent potential temperature and the potential temperature at the tropopause is proposed. Using a Gaussian approximation for the distribution of equivalent potential temperature, we argue that the tropopause potential temperature is approximately given by the mean equivalent potential temperature at the surface plus twice its standard d...
متن کاملEfficient coupler between chip-level and board-level optical waveguides.
We propose an efficient optical coupler between a submicrometer-sized silicon waveguide on a silicon photonic chip and a multi-micrometer wide polymer waveguide on an optical printed circuit board for interchip optical networks. We show low coupling loss <0.4 dB with high lateral and angular tolerance to misalignment so that coupling can be done by automatic pick-and-place equipments with high ...
متن کاملBoard-Level Single-mode Polymer Optical Waveguides
In optical interconnects, there is an increasing discrepancy between current proposals for optical backplanes, which strongly focus on multimodal waveguides, and those for very high capacity transmitter and receiver modules being realized in silicon photonics, which focus on single mode transmission systems. In this paper we present a boardlevel single mode polymer optical waveguide technology ...
متن کاملResidual Circulation and Tropopause Structure
The effect of large-scale dynamics as represented by the residual mean meridional circulation in the transformed Eulerian sense, in particular its stratospheric part, on lower stratospheric static stability and tropopause structure is studied using a comprehensive chemistry–climate model (CCM), reanalysis data, and simple idealized modeling. Dynamical forcing of static stability as associated w...
