5 We examine the key characteristics of the boreal winter extratropical circulation changes in 6 response to anthropogenic aerosols, simulated with a coupled atmosphere-slab ocean general 7 circulation model. The zonal-mean response features a pronounced equatorward shift of 8 the Northern Hemisphere subtropical jet owing to the mid-latitude aerosol cooling. The 9 circulation changes also show ...

L HE only genetic difference between the composition of a sweet corn kernel and that of field corn is due to a single recessive gene out of the hundreds or thousands of genes in corn. This gene makes the sugary condition of the kernel persist in sweet corn; or, in other words, prevents the conversion of some of the sugar into starch. The first recorded observation of sweet corn by w^hite men ap...

The key to minimizing the effects of an intentionally caused disease outbreak is early detection of the attack and rapid identification of the affected individuals. The Bush administration's leadership in advocating for biosurveillance systems capable of monitoring for bioterrorism attacks suggests that we should move quickly to establish a nationwide early warning biosurveillance system as a d...

We present measurements of anisotropy in the Cosmic Microwave Background (CMB) from the first season of observations with the Degree Angular Scale Interferometer (DASI). The instrument was deployed at the South Pole in the austral summer 1999–2000, and made observations throughout the following austral winter. We present a measurement of the CMB angular power spectrum in the range 100 < l < 900...

We have examined some of the characteristics of moisture advection and its relation to precipitation over Australia. Seasonal extremes of moisture advection have changed considerably during the latter part of the 20th century. Analysis of its skewness reveals that the relative occurrence of these events has increased. A kurtosis analysis shows that there has been a geographical shift of where t...

Atmospheric conditions at Chajnantor have been monitored since April 1995. Starting then, the National Radio Astronomy Observatory (NRAO), joined by the European Southern Observatory (ESO), Onsala Space Observatory (OSO), and the Nobeyama Radio Observatory (NRO), have operated atmospheric and weather monitoring equipment to characterize the observing conditions for a large radio interferometer ...

[1] An East Asian cold surge (EACS) is characterized by rapid advancement of a polar airmass toward the east coast of the Eurasian continent in boreal winter. Over the east coast of Asia, extratropical cyclogenesis and the amplitudes of atmospheric disturbances ranging from synoptic to subseasonal timescales are immediately enhanced as the cold air approaches. This study investigates for the fi...
