升評Medium

THE AREA OF CONVECTION PREVIOUSLY LOCATED NEAR 8.7S
159.1E, IS NOW LOCATED NEAR 10.4S 158.9E, APPROXIMATELY 690 NM EAST
OF PORT MORESBY, PAPUA NEW GUINEA. ANIMATED MULTISPECTRAL SATELLITE
IMAGERY DEPICTS PERSISTENT DEEP CONVECTION BROADLY WRAPPING INTO A
CONSOLIDATING LLCC. A 020413Z SSMI MICROWAVE IMAGE ALSO REAVEALS
SCATTERED CONVECTIVE BANDING OVER THE EASTERN SEMI-CIRCLE WRAPPING
INTO CENTER. A 022220Z ASCAT PASS SHOWS A 15 TO 20 KNOT CIRCULATION
WITH 25 KNOT WIND BARBS ALONG THE EASTERN PERIPHERY. UPPER-LEVEL
ANALYSIS INDICATES THE SYSTEM IS LOCATED IN A FAVORABLE
ENVIRONMENT WITH LOW VERTICAL WIND SHEAR AND STRONG POLEWARD
OUTFLOW. DYNAMIC MODELS INDICATE THE DEVELOPMENT OF TROPICAL CYCLONE
WITHIN THIS AREA OVER THE NEXT 48 TO 72 HOURS. MAXIMUM SUSTAINED
SURFACE WINDS ARE ESTIMATED AT 15 TO 20 KNOTS. MINIMUM SEA LEVEL
PRESSURE IS ESTIMATED TO BE NEAR 1004 MB. DUE TO IMPROVING
CONVECTIVE ORGANIZATION, THE POTENTIAL FOR THE DEVELOPMENT OF A
SIGNIFICANT TROPICAL CYCLONE WITHIN THE NEXT 24 HOURS IS UPGRADED TO
MEDIUM

呵呵南太又一隻低壓寶寶誕生了97p今天一次評級兩隻不過這隻前幾天人家我一度還以為它是一片對流雲系而已呢目前螺旋已現但結構鬆散，這隻還特別剛編號評級Low沒多久就已經在侵襲列島當地南太氣象站方面認為要等到出海後才會有比較多的發展機會。

評級Low

AN AREA OF CONVECTION HAS PERSISTED NEAR 6.9S 158.7E,
APPROXIMATELY 90 NM NORTHWEST OF BUALA, SANTA ISABEL, SOLOMON
ISLANDS. ANIMATED MULTISPECTRAL SATELLITE IMAGERY DEPICTS FLARING
CONVECTION ASSOCIATED WITH A BROAD, ILL-DEFINED LLCC. A 312333Z
ASCAT PASS SHOWS AN ELONGATED CIRCULATION WITH 10 TO 15 KNOT WINDS.
SURFACE OBSERVATIONS FROM HONIARA SHOW 05 TO 10 KNOT NORTH-EASTERLY
WINDS WITH SLP NEAR 1006 MB. UPPER-LEVEL ANALYSIS INDICATES THE
SYSTEM IS LOCATED IN A FAVORABLE ENVIRONMENT WITH LOW VERTICAL WIND
SHEAR AND STRONG POLEWARD OUTFLOW. DYNAMIC MODELS INDICATE TROPICAL
CYCLONE DEVELOPMENT WITHIN THIS AREA OVER THE NEXT 48 TO 72 HOURS.
MAXIMUM SUSTAINED SURFACE WINDS ARE ESTIMATED AT 10 TO 15 KNOTS.
MINIMUM SEA LEVEL PRESSURE IS ESTIMATED TO BE NEAR 1005 MB. THE
POTENTIAL FOR THE DEVELOPMENT OF A SIGNIFICANT TROPICAL CYCLONE
WITHIN THE NEXT 24 HOURS IS LOW.
