Click on the small picture to view a large one. Please report any broken links Cumulonimbus clouds from a flight I took in August 1 1996, over Europe.   
Cumulus Congestus over the Negev Desert, October 13 1996. This was the first rainy day of the 1996-97 winter season in Israel. I began my chase in Jerusalem, but it was hard to see anything because of the low stratus and fog over the mountains. When the clouds began to break I saw a large tower for a few minutes, but then the fog blocked my view again. I decided to go to the plains of central Israel, where I could have a better view. The tower from earlier turned to a Cb, but it was moving fast eastward. The weather was turning brighter, though a few Cumulus Congestus were still developing over the plains. This one was developing over the northern Negev Desert. 
Jerusalem, November 20 1996. Towering Cumulus turning into Cb, looking WNW. After a dry October, November finally started producing storms. This tower was forming along a cold front approaching Jerusalem in the evening, and developed to a nice Cb.  
Towering Cumulus, looking W.
Developing Altocumulus with Towering Cumulus in the horizon, looking SE over Jerusalem, December 8 1997. The large tower in the horizon developed to a severe thunderstorm in the evening. More storms developed, probably from the Altocumulus clouds. 
Stages of the development of an Alto-Cumulonimbus cloud or Altocumulus Castellanus, looking WSW over Jerusalem, January 15 1997. An unusually warm day for January in Jerusalem produced this impressive line of of ACCAS, which produced severe weather later in the day. Note the very dark and flat updraft base, and the cork-screw look of the main tower. Read my chase report. The pictures show the developing ACCAS, about 5 minutes between each picture.        
A spectacular thunderstorm over southern Jerusalem and the Judean Mountains in the horizon, with a dark anvil above from a closer cumulonimbus, looking S, January 17 1997. Read my chase report. Very unstable weather has been dominating Israel, mainly Jerusalem, for several days. A line of severe thunderstorms formed that day over Jerusalem and the Judean Mountains. The first picture shows the beautiful cumulonimbus which developed over the southern Judean Mountains, and the second picture shows the Cb which developed over Jerusalem.  
Altocumulus Lenticularis, looking WSW over Jerusalem, February 18 1997. 
Alto-Cb, looking SE over Jerusalem, February 25 1997. 
Dark cells of Altocumlus developing from a layer of Altostratus over Ein Hemed in the western Judean Mountains, looking S, February 27 1997.  
Cumulus Congestus over northern Jerusalem, looking N, March 8 1997. As I was chasing the Cumulus Congestus in the background, the cloud above me developed an ominous lowering, as seen in the first picture. Though it wasn't rotating, I decided I'll get farther away and take better shots, but by the time I got to a better spot it disappeared.     
A large Cumulonimbus over Tel-Aviv and the mediterranean coast, looking W from Nataf in the western Judean Mountains, March 16 1997. A deep area of low pressure was approaching Israel, with a very active cold front. This cloud developed along the front. It produced heavy hail and many CG lightning. Read my chase report.  
Developing Cumulus Congestus turning into a Cb later. The thick anvil of a Cb that passed earlier is seen in the horizon. Looking WNW over Jerusalem, March 23 1997. I was chasing the Cb in the background all day, and when it turned away from Jerusalem I noticed behind it this Cumulus Congestus, with a dark flat base.

the passing of the Cb above. Looking ENE over Jerusalem, March 23 1997.
Towering Cumulus, looking WSW over Jerusalem, March 24 1997. 
Cumulus Congestus over western Jerusalem, looking WSW, April 10 1997.   
Towering Cumulus building in the hot humid air of May, in the first day of the active Red Sea Trough. Looking ENE over Jerusalem, May 9 1997. Finally, the spring chasing season started. The Red Sea trough was starting to reach Israel from tropical Africa, bringing hot and humid air from the south. These large towers appeared out of nowhere around 16:30. They died in the evening, as the trough was not yet fully active.     
Developed Altocumulus clouds with virga, looking S and SE over Jerusalem, May 13 1997. The Red Sea trough was still building and getting stronger, though severe storms did not develop that day. Read my chase report.    
Developing Altocumulus Castellanus or Towering Altocumulus, May 15 1997. Looking S over Jerusalem, at about 13:00. The Red Sea trough finally became fully active on May 15. Altocumulus were developing all day, and all was set for a chase day. Read my chase report. Light rain and a few lightning bolts occured from the clouds in these pictures. Temperatures were in the low 30s C (90s F). Humidity was about 20% in low levels, but very high in mid levels. Severe thunderstorms developed from these clouds in the evening.  
Very developed Altocumulus Castellanus,
a part of the main ACCAS or Alto-Cb seen in the background, Looking
SE in May 15 1997, at about 19:15.
This ACCAS was part of the main ACCAS or Alto-Cumulonimbus
that developed over Eilat and the Arava (in southern Israel), reaching
Jerusalem from the Dead Sea. The cloud in the picture produced a little
rain and some lightning. The temperature was about 28 C. The main cloud
produced large hail for a short time, and huge amounts of lightning, about
1 every 3 seconds. The CG/CC lightning ratio was 1:2.
Virga falling from the ACCAS cloud,
lit by the setting sun. Looking SE over Jerusalem, May 15 1997, 19:25.
Just before the main storm arrived, some rain fell
from the small ACCAS cloud in the picture above, and it looked very beautiful
with the setting sun.
