QBO and annual cycle variations in tropical lower stratosphere trace gases from HALOE and Aura MLS observations
[1] We have analyzed thirteen years (1993 to 2005) of HALOE and over two years of EOS MLS observations (September 2004 to December 2006) for QBO and annual cycle trace variations in tropical H2O, HCl, ozone, N2O, CO, HF, and CH4. We use these results to develop the theory explaining both Brewer-Dobson circulation (BDC) and QBO driven fluctuations in tropical trace gases. For H2O, BDC variations...

متن کاملWave-Driven Mean Tropical Upwelling in the Lower Stratosphere
The mean meridional circulation induced by zonal momentum forcing is considered in the context of (i) a wave–mean model, in which the momentum forcing arises naturally from the explicit representation of the stratospheric wave response to lower boundary forcing, and (ii) a zonally symmetric model, in which the momentum forcing is prescribed externally. Wave forcing is confined to one hemisphere...
متن کاملThe observation of nitric acid-containing particles in the tropical lower stratosphere
Airborne in situ measurements over the eastern Pacific Ocean in January 2004 have revealed a new category of nitric acid (HNO3)-containing particles in the tropical lower stratosphere. These particles are most likely composed of nitric acid trihydrate (NAT). They were intermittently observed in a narrow layer above the tropopause (18±0.1 km) and over a broad geographic extent (>1100 km). In con...
متن کاملThe Sub-Annual Breeding Cycle of a Tropical Seabird
Breeding periodicity allows organisms to synchronise breeding attempts with the most favourable ecological conditions under which to raise offspring. For most animal species, ecological conditions vary seasonally and usually impose an annual breeding schedule on their populations; sub-annual breeding schedules will be rare. We use a 16-year dataset of breeding attempts by a tropical seabird, th...
