Celia now in the Major Leagues: a category three hurricane

25.06.2010
Tropically speaking Celia is in the Major Leagues. She's now a Category Three hurricane on the Saffir-Simpson hurricane scale and classified as the Eastern Pacific's first major hurricane. That's quite a "batting average" for also being that season's first hurricane. The other storms that formed before her in the Eastern Pacific didn't make it to hurricane status.

Both Geostationary Operational Environmental Satellites, GOES-11 (west) and GOES-13 (east) captured visible images of Hurricane Celia and Tropical Storm Darby in the Eastern Pacific on June 23, and Celia's eye was visible in them.

At 8 a.m. PDT (11 a.m. EDT) on June 24, Hurricane Celia's maximum sustained winds were near 115 mph (185 km/hr) with higher gusts. Hurricane force winds extend outward up to 30 miles (45 km) from the center and tropical storm force winds extend outward up to 115 miles (185 km).

She was located in the open waters of the Eastern Pacific Ocean near latitude 12.5 north and longitude 113.9 west. Minimum central pressure is 962 millibars. Celia is moving toward the west near 13 mph (20 km/hr) and a turn toward the west-northwest is expected over the next couple of days. Some additional strengthening is possible later today, followed by gradual weakening on Friday.

Celia's eye has appeared to be "blinking" over the last couple of days because it has been visible in some satellite imagery, then not visible. This morning, June 24, satellite imagery sees the open eye again.

Although the upper level winds appear favorable to keep Celia going, she's moving into cooler sea surface temperatures near 26-27 Celsius (78-80 Fahrenheit) and cooler as she continues tracking farther into open waters. Tropical cyclones require sea surface temperatures at least near 80 degrees Fahrenheit to maintain their intensity, so Celia will start weakening soon because one of her "power sources" (warm water) will be removed. Those cooler waters will send Celia back into the "minor leagues" by the weekend.

Im Focus: New Method of Characterizing Graphene

Scientists have developed a new method of characterizing graphene’s properties without applying disruptive electrical contacts, allowing them to investigate both the resistance and quantum capacitance of graphene and other two-dimensional materials. Researchers from the Swiss Nanoscience Institute and the University of Basel’s Department of Physics reported their findings in the journal Physical Review Applied.

Graphene consists of a single layer of carbon atoms. It is transparent, harder than diamond and stronger than steel, yet flexible, and a significantly better...

Im Focus: Strathclyde-led research develops world's highest gain high-power laser amplifier

The world's highest gain high power laser amplifier - by many orders of magnitude - has been developed in research led at the University of Strathclyde.

The researchers demonstrated the feasibility of using plasma to amplify short laser pulses of picojoule-level energy up to 100 millijoules, which is a 'gain'...

Im Focus: Can the immune system be boosted against Staphylococcus aureus by delivery of messenger RNA?

Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.

Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....

Im Focus: A quantum walk of photons

Physicists from the University of Würzburg are capable of generating identical looking single light particles at the push of a button. Two new studies now demonstrate the potential this method holds.

The quantum computer has fuelled the imagination of scientists for decades: It is based on fundamentally different phenomena than a conventional computer....

Im Focus: Turmoil in sluggish electrons’ existence

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.

We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...
