An infrared image from NOAA's GOES-West satellite showed what appeared to be a ghostly ring of clouds and no convection in former Hurricane Cristina on Monday, June 16 as the system weakened to a remnant low pressure area.
Convection is rising air that forms the thunderstorms that make up a tropical cyclone and when there is none, there are no thunderstorms to keep it going. That's exactly what happened to Cristina in the Eastern Pacific Ocean on Sunday, June 15.
At 11 a.m. EDT (8 a.m. PDT) on Sunday, June 15, Cristina had weakened to a tropical depression near latitude 20.1 north and longitude 113.3 west, about 290 miles (470 km) southwest of the southern tip of Baja California At that time the depression was moving toward the west-northwest near 6 mph (9 kph) and Cristina's maximum sustained winds had decreased to near 35 mph (55 kph).
Forecaster Brennan at the National Hurricane Center (NHC) noted that "Cristina continues to lack any deep convection, which is not surprising given the hostile environment of strong shear, cool waters and dry air."
That hostile environment took its toll on Cristina early on June 16 when the NHC declared Cristina a remnant low pressure area. At 09:07 UTC (5:07 a.m. EDT), the post-tropical remnant low pressure area formerly known as Cristina was centered near 21 north latitude and 115 west longitude.
The remnant low had maximum sustained winds near 20 to 25 knots (23 to ~29 mph/37 to ~46 kph) and was generating seas to 8 feet (2.4 meters). As Cristina's remnants continue to dissipate, NHC forecasters expect wave heights to decrease.

Atomic clock experts from the Physikalisch-Technische Bundesanstalt (PTB) are the first research group in the world to have built an optical single-ion clock which attains an accuracy which had only been predicted theoretically so far. Their optical ytterbium clock achieved a relative systematic measurement uncertainty of 3 E-18. The results have been published in the current issue of the scientific journal "Physical Review Letters".

Physicists from Saarland University and the ESPCI in Paris have shown how liquids on solid surfaces can be made to slide over the surface a bit like a bobsleigh on ice. The key is to apply a coating at the boundary between the liquid and the surface that induces the liquid to slip. This results in an increase in the average flow velocity of the liquid and its throughput. This was demonstrated by studying the behaviour of droplets on surfaces with different coatings as they evolved into the equilibrium state. The results could prove useful in optimizing industrial processes, such as the extrusion of plastics.
The study has been published in the respected academic journal PNAS (Proceedings of the National Academy of Sciences of the United States of America).
