 August 17th, 1911 continued. 



2 p.m. Browning reported the Solar Radiation thermometer broken at the noon reading. 

 It has probably been broken by a flying pebble for there is a clean hole one side, the black 

 bulb has been snapped off the Inner Thermometer, and a hole with cracks radiating from 

 it on the far side of the outer bulb completes the damage. If this was the cause of its 

 breaking the wind must have swung at the time to S.W., but this is quite possible. We 

 are shipping the spare thermometer to-morrow. (R- E- P-) 



8 p.m. Barometer continues to fall slowly. Temperature has risen several degrees. Calm 



or S.E. airs to wind of force 1. Loud sound of wind behind Cape Adare. Glaciers and 

 mountains to the S. obscured. 



The sky with the exception of that portion near the horizon has cleared. The stars 

 show fairly brightly through a thin haze. (R- E. P.) 



9 p.m. Sky overcast. N.W. breeze of force 2. (R- E. P.) 



August Mh, 1911. 



8a.m. N.W. Airs or light breeze of force 1. Sky thickly overcast with Nimbus fog. Cape 

 Adare indistinct. Spicular snow falling, (f inch up to now.) Loud sound of wind behind 

 the cape. Barometer steady. Temperature risen a little. C^aders obscured. 



(R. E. P.) 



10.30 a.m. Expecting a wind this morning I watched carefully from 9.45 to 10.30 a.m. A 

 short description of what followed may be considered as fairly typical of our winds down 

 here, though, on the other hand, we have also had all these preliminaries without any wind 

 following them. 



Since 8 a.m. the temperature has risen steadily until it is now about 4 below zero. The 

 barometer remained steady until about 9.45 when it commenced to fall fairly steeply. Until 

 9.45 the weather remained overcast with thick snow-cloud and with light airs from the 

 N.W. or S.E. About this time a gust force 5 to 4 reached me and simultaneously the 

 southern portion of Cape Adare became completely obliterated with dense snow fog 

 which moved or rather extended further northward very slowly. A similar bank of snow 

 fog was formed against the N. end of Cape Adare in triangular form between 300 and 700 

 feet. 



This gust was succeeded by one of the same strength from the N. which carried with 

 it a low drift derived from the thin veil of snow that had fallen during the night. This in 

 its turn gave place to a gust from the N.N.E., slightly stronger and carrying with it both 

 local low drift and snow at higher levels. This latter snow was quite distinct from the 

 drift and could be seen moving down the side of Cape Adare from the S.E. and then being 

 caught as it fell over the cliff and carried swiftly towards the hut. It is evidently part 

 and parcel of the Nimboid fog which drapes the peninsula. A gust from the N. followed 

 and was accompanied by low drift and then the wind backed to N.W. and Cape Adare 

 began to clear. 



At 10 a.m. a strong gust of force 5 to 6 from the S.W. carried to us only low drift 

 but drove the snow fog N. along Cape Adare until it was completely cleared while the 

 mountains to the West became faintly visible as a bluish haze. A lull followed and lasted 

 3 or 4 minutes and the S. end of Cape Adare again became obscured by the fog, but was 

 again cleared by the ensuing S.S.W. gust which drove the snow on to the sea ice to the N. 

 and brought none to take its place. 



Another lull was succeeded by whirlwinds from the S. travelling at a greater speed 

 than any of the gusts yet recorded. These were rendered very visible, almost diagrammatic, 

 by the columns of drift and snow which accompanied and were incorporated in them, 

 columns so high that their upper end was hidden in the high level fog which hangs over 

 everything, like a pall. These columns were wide apart and several were visible between 

 the cliff and myself at one and the same time.
