1 ABSTRACT 7 Responses of shallow cumuli to large-scale temperature/moisture perturbations are examined 8 through diagnostics of large-eddy-simulations (LES) of the undisturbed Barbados Oceano-9 graphic and Meteorological Experiment (BOMEX) case and a stochastic parcel model. The 10 perturbations are added instantaneously and allowed to evolve freely(More)
1 ABSTRACT Idealized dynamical theories that employ a convective quasi-equilibrium (QE) treatment for the diabatic effects of moist convection have been used to explain the location, intensity, and intraseasonal evolution of monsoons. This paper examines whether observations of Earth's regional monsoons are consistent with the assumption of QE. It is shown(More)
[1] A new framework for diagnosing mixing in cumulus convection is proposed, where the vertical evolution of the cloud mass flux distribution as a function of given parcel properties is viewed as a mapping process. Matrices that characterize this mapping process are constructed using a Lagrangian particle dispersion model embedded in a Large Eddy(More)
1 ABSTRACT 4 Observational studies suggest that the stratospheric quasi-biennial oscillation (QBO) can 5 modulate tropical deep convection. We use a cloud-resolving model with a limited domain, 6 representing a convective column in the tropics, to study the mechanisms of this modulation. 7 The large-scale circulation is parameterized using the weak(More)
1 ABSTRACT 4 A single-column modeling approach is proposed to study interaction between convection and 5 large-scale dynamics using the quasi-geostrophic (QG) framework. Vertical motion is repre-6 sented by the QG omega equation with the diabatic heating term included. This approach 7 extends the notion of " parameterization of large scale dynamics " ,(More)
1 ABSTRACT 4 A single-column modeling approach is proposed to study the interaction between convec-5 tion and large-scale dynamics using the quasi-geostrophic (QG) framework. This approach 6 extends the notion of " parameterization of large-scale dynamics " , previously applied in the 7 tropics via the weak-temperature-gradient approximation and other(More)
1 Two Madden-Julian Oscillation (MJO) events, observed during October and November 2011 in 2 the equatorial Indian Ocean during the DYNAMO field campaign, are simulated in a small-3 domain cloud-resolving model using parameterized large-scale dynamics. Three 4 parameterizations of large-scale dynamics-the conventional weak temperature gradient (WTG) 5(More)
A novel format of fluorescence immunosorbent assay based on the hybridization chain reaction (HCR) using a DNA intercalating dye for signal readout was constructed for the sensitive detection of targets, both in competitive and sandwich modes. In this platform, the capture and recognition processes are based on immunoreactions and the signal amplification(More)

Abstract Aqueous phase reactions are important, sometimes dominant (e.g., for SO 2), pathways for the oxidation of air pollutants at the local and/or global scale. In many current chemical transport models (CTMs), the transport and(More)
