RAMMASUN intensified slightly last night, making it a super typhoon with wind speed of 135 knots. It has weakened since then and is now a category 4 typhoon. At 14 HKT, RAMMASUN was situated about 1030 km (560 NM) WSW of Iwo Jima.

威馬遜於昨夜稍為增強至超級颱風強度 (135 節),但現已減弱至每小時風速 120 海里。在 14 HKT,威馬遜集結在硫磺島之西南偏西約 1030 公里 (560 海里)。

Movement Analysis 路徑分析

RAMMASUN is about to turn NE as it crosses the ridge axis. It will maintain its northeasterly movement along the northwest periphery of the subtropical ridge in the rest of the forecast period.

威馬遜即將轉向東北移動。預料在餘下時間威馬遜將沿副熱帶高壓脊的西北部向東北加速移動。

Intensity Analysis 強度分析

Current T-number: T6.0/6.5/W0.5/24 HRS
Wind shear will strengthen as RAMMASUN is subject to the westerlies. Coupled with lower sea surface temperatures and entrainment of drier air RAMMASUN will weaken and will start extratropical transition in a baroclinic environment.

現時的 T 號碼: T6.0/6.5/W0.5/24 HRS
隨著垂直風切變增強,海水漸冷和更多乾空氣的入侵,預料威馬遜將逐漸減弱並在斜壓環境下轉化為溫帶氣旋

RAMMASUN intensified rapidly last night and a round, symmetric eye is developed. At 14 HKT, RAMMASUN was situated about 1370 km (740 NM) SW of Iwo Jima.

威馬遜於昨夜急速增強,並發展出一個渾圓且對稱的風眼。在 14 HKT,威馬遜集結在硫磺島之西南約 1370 公里 (740 海里)。

Movement Analysis 路徑分析

RAMMASUN is now tracking along the weakness in the subtropical ridge induced by an arriving mid-latitude trough. It is expected that RAMMASUN will accelerate and turn NE once it crosses the ridge axis at around 20N.

威馬遜正沿副熱帶高壓脊中的弱點向北移動。預料威馬遜將會在越過約在北緯 20 度的脊線後轉向東北加速移動。

Intensity Analysis 強度分析

Current T-number: T6.5/6.5/D2.0/24 HRS
There is virtually no vertical wind shear at where RAMMASUN is situated. Also, as the sea surface temperature at where RAMMASUN is located is very suitable for storm strengthening and the poleward outflow channels keep improving due to the trough that deepens the weakness in the subtropical ridge, it is expected that RAMMASUN can maintain strength or even strengthen a bit before recurvature. Extratropical transition is expected in extended forecast period.

現時的 T 號碼: T6.5/6.5/D2.0/24 HRS
威馬遜附近幾乎沒有垂直風切變另外由於威馬遜附近的水溫頗高,而西風槽亦將令威馬遜高空輻散轉好,預料該系統將在轉向前維持強度或作少許增強在轉向以後預料威馬遜將轉化為溫帶氣旋

RAMMASUN's large area of convection consolidated today and a banding eye is developing. The storm also reached typhoon status earlier today. At 14 HKT, RAMMASUN was situated about 710 km (380 NM) WNW of Yap.

威馬遜於今天整固,組織變得更緊密,並開始發展出一個雲捲風眼。在 14 HKT,威馬遜集結在雅蒲島之西北偏西約 710 公里 (380 海里)。

Movement Analysis 路徑分析

RAMMASUN is now tracking along the weakness in the subtropical ridge induced by an arriving mid-latitude trough. It is expected that RAMMASUN will accelerate and turn NE once it crosses the ridge axis at around 20N.

威馬遜正沿副熱帶高壓脊中的弱點向北移動。預料威馬遜將會在越過約在北緯 20 度的脊線後轉向東北加速移動。

Intensity Analysis 強度分析

Current T-number: T4.5/4.5/D1.5/24 HRS
As the sea surface temperature at where RAMMASUN is located is very suitable for storm strengthening and the poleward outflow channels keep improving due to the trough that deepens the weakness in the subtropical ridge, it is expected that RAMMASUN can intensify further into a category 3 typhoon later. Extratropical transition is expected in extended forecast period.

現時的 T 號碼: T4.5/4.5/D1.5/24 HRS
由於威馬遜附近的水溫頗高,而西風槽亦將令威馬遜高空輻散轉好,預料該系統將在轉向前繼續增強至三級颱風強度在轉向以後預料威馬遜將轉化為溫帶氣旋

JMA upgraded 03W to tropical storm status today and named it RAMMASUN. At 14 HKT, RAMMASUN was situated about 740 km (400 NM) W of Yap.

日本氣象廳今天升格 03W 為熱帶風暴,並命名為威馬遜。在 14 HKT,威馬遜集結在雅蒲島之西約 740 公里 (400 海里)。

Movement Analysis 路徑分析

RAMMASUN has started its poleward turn earlier than forecast, and from steering charts the weakness in the subtropical ridge has widened. It is expected that the ridge will retreat further to the east and allow RAMMASUN to move poleward in the first half of the forecast period, after which it will encounter the westerlies and gradually turn northeastward towards the seas southeast of Japan.

威馬遜比預期提早轉向偏北方向移動,另副熱帶高壓脊中的弱點亦已擴闊。預料副高將繼續東退,從而令威馬遜沿該弱點向北移動。隨後,威馬遜將至西風帶所影響範圍,並沿已東退的副高之西北邊向東北加速移動。

Intensity Analysis 強度分析

Current T-number: T3.0/3.0/D0.5/24 HRS
As the sea surface temperature at where RAMMASUN is located is very suitable for storm strengthening (near 30 degrees) and the poleward outflow channels keep improving due to the trough that deepens the weakness in the subtropical ridge, it is expected that RAMMASUN can gradually attain typhoon strength as it travels northwards. Extratropical transition is expected in extended forecast period.

現時的 T 號碼: T3.0/3.0/D0.5/24 HRS
由於威馬遜附近的水溫頗高,而西風槽亦將令威馬遜高空輻散轉好,預料該系統可以在其北移的過程中增強至颱風程度。在轉向以後預料威馬遜將轉化為溫帶氣旋

The disturbance 94W has strengthened into a tropical depression earlier today, and is now a tropical storm. JTWC has given it a temporary number of 03W. At 20 HKT, 03W was situated about 700 km (380 NM) WSW of Yap.

在菲律賓以東的熱帶擾動 94W 於今午增強為熱帶低氣壓 03W,並在晚上增強至熱帶風暴水平。在 20 HKT,03W 集結在雅蒲島之西南偏西約 700 公里 (380 海里)。

Movement Analysis 路徑分析

The subtropical ridge to the north of 03W has developed a weakness directly above the system. It is expected that the ridge will retreat further to the east and allow 03W to move poleward in the first half of the forecast period. Currently the extended forecast calls for a recurvature along the northwestern periphery of the retreated ridge, which is the scenario predicted by most numerical forecast models.

現在有一弱點在 03W 以北的副熱帶高壓脊間。預料副高將於未來 72 小時繼續東退,從而令 03W 沿該弱點向北移動。隨後,03W 將沿已東退的副高之西北邊向東北移動。

Intensity Analysis 強度分析

Current T-number: T2.5/2.5/INT OBS
As the sea surface temperature at where 03W is located is very suitable for storm strengthening (near 30 degrees), it is expected that 03W can gradually attain typhoon strength as it travels northwards.

現時的 T 號碼: T2.5/2.5/INT OBS
由於 03W 附近的水溫頗高,預料該系統可以在其北移的過程中增強至颱風程度。
