             abstract = "When a Coronal Mass Ejection (CME) is ejected by the Sun, it 
                         reaches the Earth orbit in a modified state and is called an ICME 
                         (Interplanetary CME). When an ICME blob engulfs the Earth, 
                         short-scale cosmic-ray (CR) storms (Forbush decreases, FDs) occur, 
                         sometimes accompanied by geomagnetic Dst storms, if the B-z 
                         component in the blob is negative. Generally, this is a sudden 
                         process that causes abrupt changes. However, sometimes before this 
                         abrupt change (FD) due to strong ICME blobs, there are slow, small 
                         changes in interplanetary parameters such as steady increases in 
                         solar wind speed V, which are small, but can last for several 
                         hours. In the present communication, CR changes in such an event 
                         are illustrated in the period 1 - 3 October 2013, when V increased 
                         steadily from similar to 200 kms(-1) to similar to 400 kms(-1) 
                         during 24 hours on 1 October 2013. The CR intensities decreased by 
                         1 - 2 \% during some hours of this 24-hour interval, indicating 
                         that CR intensities do respond to these weak but long-lasting 
                         increases in interplanetary solar wind speed.",
